Description Artem S. Tashkinov 2021-02-27 13:10:36 UTC

Steps to reproduce the issue: suspend and resume.

How often does the steps listed above trigger the issue? 5.10.13 - resumes OK as many times as you want, 5.10.17 - randomly fails to resume on the second time, sometimes it's the third or the fourth time - anyways it some point it fails to resume.

When it fails to resume, the system is completely dead: CAPS lock doesn't work, the power button which normally shuts down my laptop also doesn't work.

System info:
Linux localhost 5.10.13-200.fc33.x86_64 #1 SMP Thu Feb 4 14:54:51 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
Fedora 33 x64
HP Pavilion x360 Convertible (P1F10UA#ABA)
CPU/GPU: Intel Core i5 6200U/HD Graphics 520, rev 07
Display connector: eDP

I _really_ wouldn't want to bisect the issue because it will involve building Fedora's kernel on my quite feeble laptop.

This is seemingly fixed in 5.10.19.

Comment 2 Artem S. Tashkinov 2021-03-15 16:04:39 UTC

No, it's not fixed or maybe 5.10.23 has regressed again.

Anyways with 5.10.17 I could suspend and resume for over a week, around 20 times, and with 5.10.19 and later the system dies on resume after two or three resumes.
