[SOLVED] Resume hangs after updating to Buster

[MrDeb]

During this weekend I updated Debian to Buster from Stretch and since then I cannot resume from hibernation.

I have been using s2disk for the past years without any trouble.

When I hibernate my computer everything looks good, but when I want to resume it hangs/freezes after printing

Code: Select all

Loading image data pages (226704 pages)... 100% done
...
resume: Image successfully loaded

There is a cursor blinking but I cannot do anything, except pressing ctrl+alt+del.

If I switch back to my old kernel, 4.9, resume works again but then I get issues with starting x.

I do not know if kernel 4.9 interferes with some module causing that module not to start and hence making resume work again or what it can be.

Some of the things I have tried are:

• Removed nvidia-driver
  Installed older (390) nvidia-driver
  Reinstalled uswsusp
  dpkg-reconfigure uswsusp
  Build uswsusp from source and installed it

Any help in pointing me in some direction would be much appreciated!

Code: Select all

uname -a
Linux NAME 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2 (2019-08-28) x86_64 GNU/Linux

Yesterday I googled some more on this matter and ended up on:
https://devtalk.nvidia.com/default/topi ... st/5390484

So today I uninstalled uswsusp and installed pm-utils instead. And to my big surprise hibernation/resume just worked!

So my conclusion is that kernel 4.19, nvidia-driver and s2disk are not a good match...
