Raoul,
I've divided your key config settings up into several groups.
Good. These setting are required. There are other required settings too but if they were wrong, items in this list would be hidden.
| Code: | CONFIG_MSDOS_PARTITION=y
CONFIG_EFI_PARTITION=y
# CONFIG_IDE is not set
CONFIG_SCSI_MOD=y
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_BLK_DEV_SR=y
CONFIG_BLK_DEV_SR_VENDOR=y
CONFIG_CHR_DEV_SG=y
CONFIG_ATA=y
CONFIG_SATA_AHCI=y
CONFIG_ATA_SFF=y
CONFIG_ATA_BMDMA=y
CONFIG_PATA_ATIIXP=y
CONFIG_EXT4_FS=y
CONFIG_EXT4_FS_POSIX_ACL=y
|
Unknown to me.
| Code: | | CONFIG_EXT4_FS_SECURITY=y |
Bad or not needed. | Code: | CONFIG_SCSI_LOWLEVEL=y
CONFIG_ISCSI_BOOT_SYSFS=y
CONFIG_ATA_VERBOSE_ERROR=y
CONFIG_EXT4_DEBUG=y |
SCSI_LOWLEVEL is a menu for real SCSI device support. You don't have any real scsi devices. Turning that off will remove ISCSI_BOOT_SYSFS too. I have no idea what that does but its not needed.
Anything with VERBOSE, ERROR or DEBUG in its name should be off unless you are working on that area of kernel code. Some of these options deliberately interfere with normal operation.
Evil | Code: | CONFIG_NTFS_FS=y
# CONFIG_NTFS_DEBUG is not set
CONFIG_NTFS_RW=y |
This is harmless and not related to your boot issue. It does not do what you think it does though.
You already have CONFIG_FUSE_FS=y, so | Code: | | emerge sys-fs/ntfs3g |

Raoul,
Better, but at 72 dots per inch, I can't read it.
Feel free to email it to my @gentoo.org email address, at the original resolution.

I do not do the dropbox, either, but I can see the image there. It says nothing new, kernel panic, unknown block (8,3), there are no alternative devices listed by kernel.

Hi Neddy,
I have changed the config along the lines you suggest. Same error.
Regards
Raoul

Hi Jaglover,
Can you please tell me where? If I look in file systems, I see it enabled there.
Regards
Raoul

Raoul,
Three things come to mind.
a) you have used a text editor to edit the kernel .config file at some time.
This often produces an illegal .config, as some menuconfig entries change a lot of lines in the .config file.
The chances of getting this right by hand is close to zero as many .config file options are not exposed directly in menuconfig.
If this applies, throw away the .config file. It cannot be fixed.
b) you need CONFIG_SATA_AHCI_PLATFORM=y
I have a feeling that when you set this, you also turned off ext4 support, so if it was fixed, you wouldn't know.
c) time has stepped backwards on your system, so make is confused.
make is lazy. When a binary file exists, make checks all the dates on the files used to build that binary. If all the files are older, the build is skipped.
However, if you make a binary, time steps backwards then you change one of the files needed to build that binary, make will skip the build.
You can force a rebuild by starting with then there are no binaries in the kernel tree and everything is remade.
There is a fourth thing ...
I have very similar hardware to you. I would expect my kernel to mount root on your hardware.
We can try that next, if none of the above helps.

Hi Neddy,
a) confident I have not edited config in any way. Only via menuconfig
b) Just tried this and check ext4 enabled. No change.
c) I did this just before b). I did distclean. I assume that is what you meant.
d) That could be an option.
One further option is to use genkernel to get a working kernel and then use that config to make it manually.
What do you think?
Regards
Raoul

make distclean is not a valid make target on kernel sources.

Raoul,
Your kernel is Linux/x86 4.6.2-gentoo, mine in Linux/x86 4.6.0-gentoo.
Put my kernel .config into your 4.6.2-gentoo kernel,
do | Code: | make oldconfig
make clean |
Then build and test in the normal way.
As I use the /no-multilib/ profile my kernel is missing 32 bit support, which you have set.
| Code: | | CONFIG_IA32_EMULATION=y |
You may want to add that.
Xorg will not start for you. You use the nVidia binary blob, I use nouveau.
Still, if root will mount, that's a success.
My lspci -k, you won't need that, i just to show the similarities between our hardware.

Hi Neddy,
Thanks for those files. I have followed your instructions and also rebuilt the kernel. So now some REALLY weird stuff is happening.
1. If I use root=/dev/sda3 in my 40_custom file for grub.conf, then the boot fails. What is cool now is that the font is much smaller so I see higher up the error and it says that /dev/sda3 is not a valid root and it fails with error -6. Further, it suggests other partitions one of which is /dev/sdb3. Now I KNOW there is NO sdb3 as per below.....
blkid:
| Code: | /dev/sda1: UUID="2bec8d1f-b01c-4fdf-90c0-dae5b0ec4d38" TYPE="ext4"
/dev/sda3: UUID="1afad494-4d1e-426f-8709-d0d54ab8c6d3" TYPE="ext4"
/dev/sda5: UUID="bb269c0b-6ddb-4402-8085-5131443ad6a2" TYPE="swap"
/dev/sdb1: LABEL="/System" UUID="b0b84e74-f072-4827-9e77-c4f8d6ed8250" TYPE="ext4"
/dev/sdc1: UUID="2dd4020a-f93b-43fc-a087-387cc01fdc19" TYPE="ext4" |
fstab:
| Code: | # /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=1afad494-4d1e-426f-8709-d0d54ab8c6d3 / ext4 noatime,discard 0 1
# swap was on /dev/sda5 during installation
UUID=bb269c0b-6ddb-4402-8085-5131443ad6a2 none swap sw 0 0
UUID=2dd4020a-f93b-43fc-a087-387cc01fdc19 /Data ext4 auto,noatime,nofail,sync 0 1
UUID=b0b84e74-f072-4827-9e77-c4f8d6ed8250 /System ext4 auto,noatime,nofail,sync 0 1
#UUID=2bec8d1f-b01c-4fdf-90c0-dae5b0ec4d38 /Ubuntu ext4 auto,rw,sync 0 1 |
2. So then, on a hunch, I changed my 40_custom root to /dev/sdb3 and lo and behold, the thing boots. I can log in as me. I can confirm that the directory structure of root is for the gentoo installation not for anything else. However, when I try to emerge it tells me there is a fatal python erro and it failed to open /dev/urandom.
When I use a chroot into the gentoo system, I can run python-updater successfully without it requiring any new packages.
Now I am REALLY confused.
Regards
Raoul

Raoul,
Oops ... missing /dev entries is my fault. That kernel is intended to work with a static /dev
You don't have one of those, so /dev will be empty. Almost nothing will work.
However, it did provide some useful diagnostics.
You can turn on DEVTMPFS and the option to mount it that will appear in my kernel, or apply
the lessons learned to your kernel.
With DEVTMPFS mounted, /dev will be populated and things will be more normal for you.
My kernel uses the nouveau driver, so you now use the nouveaufb console. Hence the smaller text.
Now that you see the list of possible devices, your own kernel may boot when you tell it root is on sdb.

Thank you Neddy for the tips. All now works even with nvidia enabled. The Gentoo system is naming things as sdb......never had that happen before.
Still getting some instability but I will start a new thread for that.
Thanks too Jaglover for your input.
Regards
Raoul
