Description:
Since a Kernel update a few weeks ago, my laptop freezes when resuming after hibernation. It seems to handle the resume process normally but at the moment I should see Gnome login screen, I get a black screen with just a white underscore instead. I can't do anything at that point and I have to hard reboot.

journalctl gives nothing between the beginning of the resume and the crash, as if it never happened.

This started with one of the early versions of 6.2 branch but I'm not sure which one. All 6.2.x versions since then have the issue. Everything works fine with LTS Kernel.


Steps to reproduce:
- hibernate
- resume
- wait until the resuming process should finish: black screen instead of e.g. Gnome's login screen
This task depends upon

Failing to resume from sleep is a common kernel problem, but very hardware specific...and you haven't specified *any* details about your hardware. Please review the bug guidelines [1] to see what's required for a good bug report. Anyway, it doesn't matter much because this is a kernel regression. Here is the general advice for debugging kernel regressions [2]. Please let us know what you find out.

I bisected linux-git and found the issue seems to be caused by commit da6d9c8ecd00. I reported the bug upstream: https://bugzilla.kernel.org/show_bug.cgi?id=217442. I think we can close here, sorry for the noise.

Good work bisecting! That commit is listed here [1] and a proposed fix has been posted [2].
