[EN] Hibernation problem
« on: 2023/12/02, 21:33:11 »
Hi all,

I have a Ryzen system since a few years which couldn't be hibernated by Debian 10, 11, and 12.
Siduction is the first one that could actually hibernate it although in a little bit funky way:
  • Sometimes pm-hibernate returns without hibernating but wil hibernate properly if the command is launched again
  • Sometimes hibernate without power shutdown (manually switching off the system is then ok)
  • Sometimes it works exactly like pm-hibernate is supposed to do it.
Since a few days pm-hibernates fails more often and in a way that requires a forced shutdown.
At this time, a have never ending switch between X and the console with a message that says something like "unable to create image" without the possibility to CTRL-C the pm-hibernate process.
I do have a swap, which is a little less than twice my memory size.
I suspect the last kernel upgrade being linked to the occurrence of this problem.
Any idea ?

Can you confirm this by booting another kernel?

Sorry for being late.
linux-image-6.6.6-1-siduction-amd64   fails systematically to hibernate on my box :  after pm-hibernate, either I my session is interrupted and I am sent to login screen, screen switchs endlessly off and on or after reboot I have the login screen instead of my session.

linux-image-6.6.4-1-siduction-amd64 seems to be fine.

Mh, maybe dmesg or journalctl showing some error or failure messages?

Additionally to what hendrikL said have you tried invoking hibernate via systemd?
Does
Code: [Select]
# systemctl hibernate
fail too?

Also just out of interest, what does
Code: [Select]
$ dmesg | grep "ACPI: PM: (supports" say?

This shows which sleep states are supported by your UEFI/BIOS https://en.wikipedia.org/wiki/ACPI#Power_states S4 may indicate that your device has a special sleep state for hibernation, instead of switching it off (i.e. entering S5).
IIrc this can be broken on some devices and lead to trouble, but I'll have to look this up I might confuse something here.

But looking at your output for 6.6.6-1, especially because of these lines
Code: [Select]

déc. 13 07:29:28 logodenn kernel: PM: hibernation: Memory allocation failed
déc. 13 07:29:28 logodenn kernel: PM: hibernation: Error -12 creating image
I am wondering if you have a large enough swap space for hibernation.

Could you also please post the output of
Code: [Select]
inxi -mj
so we can check.

Otherwise I'd suspect in fact a bug in the kernel because this line here
Code: [Select]
déc. 13 07:29:27 logodenn kernel: CPU: 0 PID: 16838 Comm: pm-hibernate Not tainted 6.6.6-1-siduction-amd64 #1  siduction 6.6-6
Looks like the beginning of one of those backtrace like blocks the kernel puts to dmesg if something went wrong.
Is/was there something in your logs (dmesg/journalctl) after your snippet that looked similar to the stacktrace here https://www.kernel.org/doc/html/v5.8/admin-guide/bug-hunting.html ? (It might have been ripped into multiple parts by the other messages)

There is normally more than enough swap to hibernate, but I'll check how much of it is used before hibernating.

I have not tested. I'll try it at the next reboot.

Sorry for the late reply.

I guess reporting it would fall into towos domain, because bug reports from (patched) distribution kernels against the upstream kernel are usually ignored.
I'm gonna have a look at the kernels regression tracker later (maybe the problem is already known).

In any case I'd recommend you to check if your problems disappear with newer kernel versions (maybe you are lucky).

Mh, Kernel 6.6.4-1 is an old one, it should be 6.6.8-1, please test with that kernel!
