Public bug reported:
In the last year my PC suffered from increasing problems while going
into standby. Sometimes it worked, sometimes it failed. Each kernel
update added to the failure chances. For some time I could work around
that by using s2ram. Finally standby stopped working completely after an
update.
Recently, after installing one more kernel update, standby suddenly
worked perfectly fine. The following update killed standby once more.
This is a list of the three kernels on my system:
5.4.0.53 - Standby fails
5.4.0.54 - Standby works
5.4.0.56 - Standby fails
Please tell me if I can help to analyze the problem.
