In sys-kernel/pf-sources-2.6.39_p4 this happens when I try to resume from hibernation (using tuxonice):

Code:

Then the system happily continues booting up. Anybody else has this problem?

Are you guys kidding or something? His log just show that the TOI helper `/sbin/tuxoniceui_text' is not loaded... Are you booting from an initramfs? If so, just make sure to include the helper in your initramfs. If not, I remember not to bother with the helper path name of the helper before kernel .38. However, if I remember well, since kernel .38.[something] the path name is required in the TOI kernel config. And then come the deafult path name which is `/sbin/local/tuxoniceui_text'--notice the `local/`, just remove it and you'll be fine with it.

I have the same problem. Just built TOI kernel from the gentoo repo (2.6.37) and it boots fine. When I manually run the hibernate.sh script (getting the buttons to function and call the script is another nightmare im sure ill have to deal with another time) it suspends to disk and shuts down.

When I boot my system again it says the path which CLEARLY EXISTS cannot be found. This is retarded guys seriously. Wtf?

Failed to launch userspace program '/sbin/tuxoniceui_text': Error -2

I have rebuilt the kernel like 90 times changing the path to multiple things each failing the same. I even left it blank in which case I got a not configured error instead. Yay. No I am not using an initramfs.

Any help on this is greatly appreciated as not finding a file that I know exists is clearly a case of shitty config/coding.

thx

that doesn't say it couldn't be found, just couldn't be launched :wink:

I get the same message for a second, and then the machine wakes from
hibernation normally

my kernel is
Code:
2.6.39-pf4 #1 SMP PREEMPT Wed Jul 13 08:25:53 EDT 2011 i686 Intel(R) Core(TM)2 Duo CPU L7100 @ 1.20GHz GenuineIntel GNU/Linux


I'm running x86, not amd64 if that's relevant ...

Any idea why it can be found and not loaded? I'm running the latest tuxonice-sources that emerge lets me use by default (2.6.37). After I get this message I get the following:

Launch userspace program failed.
Stopping fuse filesystems.
Freezing user space processes ..done
Stopping normal filesystems.
Freezing remaining freezable tasks done
Reading kernel & process data...
ibm trackpoint stuff
20%....40%.....60%.....80% <------------- just hangs at this point.

Any idea what I'm doing wrong here? I've rebuilt the userspace app after running from the TOI kernel just in case it used kernel sources but same result....

edit: I am also runnng x86 32bit. Its a core 2 duo 2.00ghz

I don't know what could be your problem.

if you have the time and inclination, you could try the pf-sources 2.6.39 kernel
which I think has a newer TOI ...

I am suspending to a swapfile rather than partition but I doubt that is
causing your trouble.

So I've switched to using tuxonice-sources 2.6.38-r2 by unmasking. I was using 2.6.37 previously. This fixed my issue with compiling WIRELESS_EXTENSIONS which makes me think that the previous kernel was simply broken. However my issue with hibernation remains. I've followed the gentoo tuxonice guides, I've configured the dedicated file for suspending (not swap partition or swap file) and i've gotten acpi to handle keyboard events to trigger the hibernation scripts. Hibernate-ram works just fine. Hibernate simply doesn't resume due to "unable to load usermode blah blah".

Seriously I'm just not sure what I'm doing wrong here. I've spent all day yesterday rebuilding the kernels and trying different things. All settings are as they are supposed to be, acpid is emerged and responding to key presses and calling necessary scripts. The path to the userui program is correct. I've even hardcoded it in /etc/hibernate/tuxonice.conf. I'm not using an initramfs.

I've built the kernel from pappy seeds for 2.6.38 tuxonice edition. I've gone over everything so many times now. The issue revolves around this stupid ui application simply NOT being launched.

I vaguely recall having this problem in the distant past. Excerpt from my kernel .config:

Code:
CONFIG_TOI_USERUI=y
CONFIG_TOI_USERUI_DEFAULT_PATH="/sbin/tuxoniceui_text"


And my boot commandline (for grub2):

Code:
linux   /boot/kernel-2.6.38-tuxonice root=/dev/sda ro resume=swap:/dev/sda:0xdd9c000


I think the element "root=/dev/sda" may be important -- it specifies which device is the root fs, so the kernel can actually find "/sbin/tuxoniceui_text".

I've the same in my kernel configs.

As for the grub boot line I have the same thing, with the exception that my root partition refers to the partition /dev/sda3 not the general disk /dev/sda. I don't see why it wouldn't be able to reach the file. Someone earlier said it wasn't that it couldn't be found, but that it couldn't be loaded/launched.

Please verify that:

Code:
# cat /sys/power/tuxonice/user_interface/program
/sbin/tuxoniceui_text

The obvious thing to try is to switch to tuxonice-sources and see if you get the same error. If not, it's a problem with the pf-sources . If you do, there's something wrong with your setup, which in principle is easy to correct ...

Sorry I was piggybacking onto this thread so I wouldn't end up making another. I'm using gentoo tuxonice-sources 2.6.38-r2. This + pappy seeds for tuxonice 2.6.38

Does you get the same result if you use 'pm-hibernate' from the pm-utils package instead of 'hibernate' ?

Or

Code:
# echo 1 > /sys/power/tuxonice/do_hibernate


?

BTW, even if the userspace ui program doesn't run, hibernate should still resume successfully, and it will showing progress in the kernel log like

Code:
Reading caches...
...20%...40%...60%...80%...100%


Are you sure there are no other errors, besides the complaint about the userspace program? One common problem is to have kernel compression driver (e.g., "lzo") as a module, but if you don't have an initramfs it can't be loaded on resume -- the solution is to build it into the kernel.

I remember trying pm-hibernate and not getting anywhere either but I only tried it once and don't recall exactly what happened. I have all crypto routines built into the kernel.

The only error that I notice on resume is that the userspace program cannot be loaded. As for the resuming anyway it doesn't work for me. I do however get the progress 20%...40%.. etc but it always seems to hang on 80%. I had waited for a few minutes a few times but it never got further. Is there any reason that this might occur?

Edit:

I'm adding the part of my grub config that has the resume variable:

resume=file:UUID=1a8320606d5f40d6a7a3b4dd32f4d690:0xfa118

I am using the dedicated files method which I echo'd TuxOnIce into first followed by concatenating 3G of /dev/zero . This file is in / and I used the guide to determine the file offset. echo /suspend_file /sys/power/tuxonice/file/target followed by cat /sys/power/tuxonice/resume. The output was UUID=1a8320606d5f40d6a7a3b4dd32f4d690:0xfa118 which I put into the resume variable after file

I don't think the hibernation file is all zeroes. When I used a hibernation file I created it with the procedure here.

You can try a swapfile instead to see if the hibernation file is the problem. I use a swapfile now so hibernation works properly through upower+xfce4-power-manager.

I tried your method of determining the suspend file location on disk and its definitely easier than the guide's method. However the output was exactly the same:
root=/dev/sda3 resume=file:UUID=1a8320606d5f40d6a7a3b4dd32f4d690:0xfa118

which at least is consistent. The only thing I don't get is why I get UUIDs instead of /dev/sda3:0xfa118. perhaps I'll change file:/dev/sda3:0xfa118 and see what happens. I'll try that as soon as I get back home. Other than that the resume stops at 80%..... still not sure whats going on there.

I haven't tried the swapfile but I initially tried this using a swap partition which failed in the same way. I'm thinking that isn't the issue. Of course my swap partition is 512MB so maybe there is something to that though. However resizing a partition on an up and running system isn't something I want to add to my misery which is why I decided on using a dedicated suspend file.

Right, so I would use a swapfile instead of a swap partition. Just follow the mkswap man page, and put it in your /etc/fstab .

I also vaguely recall not being able to get UUID's to work for files, so I just specified the device name, as shown in my boot commandline above.

From your example grub.conf
Quote:
linux /boot/kernel-2.6.38-tuxonice root=/dev/sda ro resume=swap:/dev/sda:0xdd9c000


Does it matter that you aren't specifying the actual partition? swap:/dev/sda as opposed to /dev/sdaX ? I will try to change my file from uuid to /dev/sda3 but I want to be sure that that is the correct notation. Logically you should specify /dev/sda3 but you're example is missing that particion number.... Why?

I have a partitionless disk, so my root fs is on /dev/sda instead of /dev/sdaX .

I have the exact same problem and dmesg output using pf-sources-2.6.39_p4 and 3.0.1. I sent a report upstream to them. They got back to me saying they would notify the devs at Tuxonice. The problem appears to be lzo related. Disabling compression either in the kernel or via the hibernation script config file allows resume to proceed normally but extremely slow. I determined the issue to be lzo related because if I attempt to build my kernel or initramfs with lzo compression instead of gzip the build fails with errors.

There were a couple of threads over at the Arch Linux forums discussing this issue.

Perhaps you too can file an upstream bug report (not to gentoo devs) so they can see this is affecting many users.

I hope this helps.

Ciao

I believe this to be a problem with tuxonice apparently not going well with the bfs patch. Using tuxonice alone, these issues go away and everything is ok.
