This happens every time - at random times after resuming from suspend/hibernate the system freezes and only power cycle helps. I’ve found some info information about last freeze that happened in kern.log: Mar 31 12:13:06 gingerblade kernel: [33692.874653] watchdog: BUG: soft lockup - CPU#2 stuck f…

as far i can see - this should make sense only when lots of GPU RAM is being wired/allocated at the time of hibernate/suspend event, right? I have 8GB GPU RAM and only 1 GB is being used normally by Xorg, Chrome and some other apps. Do you think i should try configuring second option using /proc/dr…

Option one, which is the default (the one you should be using right now), is limited by functionality. As said, I’d give it a try. Won’t hurt and is easily revertible. The only thing to watch out, is to have enough space on the drive/mountpoint.

In general. You are hitting a crash. So all we do here is try. Only nvidia can analyze the crash dump, that came with your bug report.

ok, so i’ve updated to most recent driver from PPA, i’ll try configuring option #2 and hibernating later today - if it’ll crash again i’ll provide another nvidia-bug-report.log.gz. Can i expect it would be analyzed by Nvidia after that?

I’d say - Hope dies last ;-) However for increased attention you then could also send it to: linux-bugs@nvidia.com (with a reference to this topic).

Ah, I read the changelog, but nothing I understood about suspend/resume improvements, except the automatic installation. For xyapus: If you want to give it a try, make sure you purge all nvida-driver ppa files (apt purge nvidia* libnvidia*), before installing via .run file. And stop the X server b…

There was a lot of intertwined behavior around VT switches and suspend/resume that I tried to untangle for the 465 series. All of it hinges off of the NVreg_PreserveVideoMemory=1 module parameter, which is still disabled by default in most cases. The suspend/hibernate/resume systemd units are requir…

Thank you for the explanation @aplattner ! @xyapus you find that driver and notes here for example: Current graphics driver releases

While using 460.67-0ubuntu0~0.20.04.1 i tried manually following this Configuring Power Management Support guide and installed required systemd services. I’ve set up /tmp to use tmpfs of proper size using the /etc/systemd/system/tmp.mount so: $ mount | grep /tmp tmpfs on /tmp type tmpfs (rw,nosuid,…

There were some improvements I made in the 465.19.01 beta for suspend/resume with the power management stuff enabled. I know it might be difficult to test the beta if you’re using a PPA but would it be possible to give it a try?
