This one is an elusive question. When I power the computer up and boot on Gentoo (UEFI, through rEFInd), they keyboard, a Corsair USB K70 RGB, takes around 5 second on the udev devices line in the boot, then proceeds to work normally. Now comes the question, when I reboot the computer instead of powering it off, the udev devices line takes around 30 seconds and now the keyboard doesn't work anymore. I have to shut down the computer and turn on for it to work again.
What creepy issue could be causing this? Something that happens maybe on the BIOS that is not initializing it correctly?

Any ideas here?

Thank you,
Nelson

Some updates:

I've tried to change many options in MoBo EFI and nothing changed. I removed rEFInd as the bootloader and the same problem still occur. I've changed memory modules (because in some boot times, messages about checking for memory corruption every 60s appeared in the first line of the boot). Nothing seems to changed.
So, I download linux Mint liveCD and since it boots correctly every time, I'm not inclined to believe it is something wrong in either the kernel configuration or in the initram (which I used for FakeRaid).

Bottom line: What can be causing two booting process, consecutively done and without making any changes, detecting different hardware and displaying different messages? Isn't the boot time a deterministic process?

Thank you,
Nelson

nelsonwcf,

The two process differ in the way the hardware is reset.
When you power up the system, everything gets a reset pulse from the PSU. This hardware reset is missing when you do a shutdown -r now.

It gets worse. The boot process is not deterministic. Its mostly event driven.

I suspect the problem is USB related and changing the module load order will change things.
From a cold boot, post your kernel .config file - it needs to go onto a pastbin site.
The dmesg output - it needs to go onto a pastbin site too.
The output of lsusb -vvv - it needs to go onto a pastbin site too.
The output of lsmod

Now it gets harder ...
We need dmesg and lsmod after a restart too but your keyboard won't work.

Can you ssh in to get that?
Alternatively, a bit of a hack put the following into
/etc/local.d/savefiles.start and chmod +x /etc/local.d/savefiles.start

Code:
#!/bin/bash
dmesg > /root/dmesg.txt
lsmod > /root/lsmod.txt
# we only want this to run once
rm /etc/local.d/savefiles.start

When you regain control post, those two files.

If it helps any, I've been through something similar with USB. It got very picky about module load order.
My workaround was a file in /etc/local.d/ that removed the USB modules then reloaded them in the right order.
This caused a keyboard not working sometimes issue too.

Hi NeddySeagoon,

Thanks for the help. Here are the pastebinned files:

http://pastebin.com/EwSFZLPP - .config
http://pastebin.com/HdNpCeem - dmesg
http://pastebin.com/BpQJvzPe - lsusb -vvv
http://pastebin.com/4ZDXCLcJ - lsmod

In this boot, the USB keyboard didn't work so I used an PS/2 keyboard (without disconnecting the USB keyboard) to be able to capture the problems.
If you need something else, just request it and I will post it here ASAP.

Thank you for the help.

nelsonwcf,

I want to compare a working dmesg with a USB not working dmesg.

nelsonwcf,

Your lsusb is interesting.

You have a total of four USB root hubs but only one appears to be used.
Code:
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub


Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 008: ID 0b05:1825 ASUSTek Computer, Inc.
bDeviceProtocol         1 Bluetooth
  MaxPower              100mA
Bus 001 Device 003: ID 1532:0043 Razer USA, Ltd Razer DeathAdder Chroma (mouse)
 MaxPower              100mA
Bus 001 Device 002: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS
  MaxPower                2mA
Bus 001 Device 010: ID 046d:082d Logitech, Inc. HD Pro Webcam C920
  MaxPower              500mA
Bus 001 Device 009: ID 045e:0719 Microsoft Corp. Xbox 360 Wireless Adapter
 MaxPower              260mA

There is no keyboard there either.
As this is a USB 2 root hub, its allowed to supply 500mA for all bus powered devices.
The load there is 962mA.

As you have a Razer DeathAdder mouse, I suspect you have the matching keyboard too.
That probably needs another 500mA for all the LEDs

USB 3 ports can supply 900mA for all for all bus powered devices.

As a first step, redistribute your USB devices to comply with the bus power part of the USB spec.
Having said that, different USB root hub arrangements do different things in the face of overloads.
Some do load shedding, some refuse to work at all, others do nothing.

All the missing device numbers indicate that the devices that are there didn't start first time.
With a clean start, the numbers will be sequential.

Hi,

I had some trouble getting the keyboard to work again on linux so I disconnect every single USB device from my USB ports with the exception of the mouse and keyboard.

Here are the pastebins for dmesg and lsmod with the keyboard working.

http://pastebin.com/PvidSA2J
http://pastebin.com/1RdF0UKj

The USB 2.0 load seems huge but there wasn't really anything plugged there, which makes me wonder what was happening. In addition, if the problem was overloading, why would the devices work correctly in Windows 10?

Any other insights on what could be happening here?

and again, thank you very much! very nice way of tracking the problem up!

nelsonwcf,

The lsmod outputs are identical between working and non working.
That tells that the module load order has not changed.
The first loaded module is at the bottom of the list.

Something that stands out like a sore thumb in dmesg is the difference in timestamp formats.
I've never seen what appears to be the incremental format in your reboot dmesg.

Your mouse and keyboard are now both on a USB3 bus.
Code:

[    1.271970] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002
[    1.271971] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1
[    1.271972] usb usb1: Product: xHCI Host Controller
[    1.271972] usb usb1: Manufacturer: Linux 4.4.26-gentoo xhci-hcd
[    1.271973] usb usb1: SerialNumber: 0000:00:14.0
...
[    1.630934] usb 1-7: new full-speed USB device number 2 using xhci_hcd
[    1.798091] usb 1-7: New USB device found, idVendor=1532, idProduct=0043
[    1.798093] usb 1-7: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[    1.798093] usb 1-7: Product: Razer DeathAdder Chroma
[    1.798094] usb 1-7: Manufacturer: Razer
...

[    2.222555] usb 1-8: SerialNumber: 1302B014AEBA042355CE11AEF5001946

Full speed means 12Mb/sec which is USB1.

Its clearly not a power issue an there is 900mA available.

Looking at your not working dmesg (note the timestamps)
Code:
[  +0.233382] usb 1-6: new full-speed USB device number 2 using xhci_hcd

This tells a different story to lsusb. Here, its all on a USB3 root hub.

I guess
Code:
[  +0.002516] usb 1-8: new full-speed USB device number 4 using xhci_hcd
[  +6.178167] usb 1-8: unable to read config index 0 descriptor/start: -110
[  +0.000002] usb 1-8: can't read configurations, error -110

Is your keyboard, since its not working.

Notice device numbers 4,5,6 and 7 being used trying to get the device to work.
That ties in with lsusb too.

When you get into this state, does unplugging the keyboard, waiting a few seconds, then plugging it back in fix it?
The keyboard will get a hardware (power cycle) reset.

As your keyboard contains decorative LEDs, watch them during a restart. Do they go out?

The USB port that your keyboard is connected to, how is it powered?
Some motherboards have a jumper to select between 5v and 5vSTBY.
The former goes off in standby, the latter is always present when the system is connected to mains power.
Its main use is to be able to bring the system out of standby by pressing a key.

nelsonwcf, NeddySeagoon,

the problem can come from some Usb and/or keyboard supports who need to be in the kernel image or in the initramfs. With ArchLinux I had to put some modules in the initramfs for my Usb mouse working after boot with Gpm, the copy and paste mouse server at the console. Otherwise it was not working but I only had to restart the service. So, something was missing at boot time who was there after it.

The fact that Linux check for memory corruption every 60 seconds do not mean that your memory surely have something wrong. This mean that those 2 options are on in your kernel configuration:
Code:
CONFIG_X86_CHECK_BIOS_CORRUPTION=y
CONFIG_X86_BOOTPARAM_MEMORY_CORRUPTION_CHECK=y

Neddy,

I'm going through checking my BIOS and motherboard right now because after your comments, I found out that four ports that should be USB 3.0 are acting like USB 2.0 so this problem may be related. As soon I finish checking BIOS options and the if the connectors are in the right place I will give you more information.

Logicien,

There is a driver for this keyboard in corsair forum but the randomness of the keyboard being recognized or not is the problem. For example, the keyboard works in refind bootloader normally and also in the BIOS. Only when the kernel boots, the keyboard most of the time doesn't work but in some cases it is recognized. That is what the mystery is. I already installed the ckb driver but nothing happens if the keyboard doesn't start. Doesn't matter if I disconnect it and then reconnect. It is simply not detected.

I will get back to you soon.

Thanks!

I don't know how to decode the output files like Neddy's doing, but I have a question which may be pertinent.

Is your keyboard connected directly to a usb port on the motherboard? Meaning, no usb hub in the middle.

I had keyboard issues for awhile too, wound up calling paid support. They found out I had an external powered usb hub on my desk. When I moved it to direct connection the problem went away.

nelsonwcf,

There is a corsair driver in the kernel, which you are not using.
Code:
# CONFIG_HID_CORSAIR is not set

Since you only have this problem at reboot, not cold start, its unlikely to be that.
A missing driver is normally permanent non operation.

You might like to add it at your next kernel rebuild.

1clue: yes, right now it is but I've tried both. Same issue.

NeddySeagoon: yes, I saw this option but it is for old models only, not for this one.

As I told you guys before, I started tracking what was wrong with my USB ports so I plugged my pen drive in all of them and used a Windows tool (because everything seems to be working correctly on windows) and tracked all the ports. Something very weird is happening, sometimes the port is detected as USB 2 and sometimes as USB 3 in the USB Tree list. I went back to EFI BIOS and changed the legacy USB port from disable to auto to see if it fixed something.

The first time I booted on linux, it showed the following message:

http://picpaste.com/20161130_164426-EedvyzJG.jpg

Definitely something is wrong but I never saw such message but based on what is happening, it could be related to my keyboard not beings deterministically detected (similar messages happened before but I though it was something with me playing with the kernel settings).

nelsonwcf,

Do you have any USB3 devices?

A few USB3 hubs only run at USB2 if the first detected device is not USB3.
That's not supposed to happen, its a hardware bug.

If you have a USB3 device (I didn't see any) boot with nothing except the USB3 device connected.
This should force the USB hub to start in USB3 mode.
Now connect all the slower devices - order does not matter.

Something a bit more invasive. Remove USB2 support for the kernel, or unload the EHCI and XHCI modules, then reload only XHCI.

Code:
Module                  Size  Used by
x86_pkg_temp_thermal     4727  0
e1000e                164467  0
fuse                   76451  1
hid_generic             1385  0
usbhid                 25246  0
xhci_pci                4714  0
xhci_hcd              109801  1 xhci_pci
uhci_hcd               22171  0


Hmm
Code:
CONFIG_USB_EHCI_HCD=m
So the USB2 root hub driver is not loaded.
As you don't have any USB 1 hardware, uhci_hcd is not used.

Try
Code:
modprobe -r xhci_hcd && modprobe xhci_hcd

Keep in mind that's your USB hardware driver, so you may be without a keyboard after that completes.
In theory, it will cause all your USB devices to be restarted.

Okay. I did the things you suggested and I couldn't really see any difference:
- Tried to play with XHCI and EHCI and nothing changed;
- Tried to unplug and plug the keyboard again. When the keyboard doesn't work, normally the LED lights go off. When I unplug and plug it, the lights go on again but the keys still doesn't work;
- Tried to change some options in the BIOS but nothing changed.

Then I decided to try a different approach. I booted Linux mint and copied its .config to my current kernel and ran "make olddefconfig". I compiled the kernel (which took a lot of time) and then ran "genkernel initramfs --mdadm" because I need it for Fakeraid. That portion was interesting because it took almost 3 minutes for it to complete when previously it took less than 8s. After that, I Installed both new kernel and initramfs and rebooted. It took almost two times the boot time boot it booted and the keyboard worked correctly. Maybe it was just luck so I rebooted and it worked again correctly. I powered it off and turned it on and it worked correctly again. So far for now, it is working correctly. Now, my kernel is completely bloated with useless drivers and modules but it boot.
Interestingly, this new message appeared while still in the initramfs.img:

>> Activating mdev
>> Loading modules
:: Loading from pata then loading from sata, from scsi, from usb and there, the usbhid and hid-generic took around 5s to load then it proceed forward. This time, the initializing udev devices, the one who normally took 10s to proceed when the keyboard worked and around 20s when it didn't, this time takes 1s.

This solution may indicate that the problem was in the hardware configuration. Now, what could I have done differently that move loading the modules to the initramfs instead of the regular boot but which make the keyboard work correctly?

The problem with the rcu_shed didn't show up anymore so far.

This is eluding me because I want to clean up the kernel but I don't know what I can remove or not and;
why did genkernel this time took so long to finish and generated a more complete initramfs?

You know one thing, Linux can manage your keyboard on Gentoo. With your new kernel configuration taked from Mint you have to circle what was missing (maybe what was to much) in your previous kernel configuration. It may be a Usb and/or an Input support.

I suppose that your actual kernel is bigger and have more modules than before. It explain why your initramfs is bigger too. More stuff apply to your material. Generic kernels and initramfs are big.

When try to slim the kernel, you can remove without problem the support for cable and wireless Ethernet who do not apply. I hope you will find why Mint kernel work and not you own one so you will be able to use your previous one with corrections.
