Comment # 29 on bug 1202138 from Marius Kittler

Now the machine powerqaworker-qam-1.qa.suse.de has started to show the same
symptoms. To my knowledge it ran just fine on Leap 15.4 with the standard
kernel but for some reason it is unstable now as well. It has already crashed 2
times this week. Like on the other hosts there's no useful information in the
journal (see https://progress.opensuse.org/issues/120004 for the related ticket
on our side).

I find it quite weird that not all machines showed the symptoms directly after
the upgrade to Leap 15.4. As stated in the bug description, only
qa-power8-4-kvm.qa.suse.de appeared to be problematic at the beginning while
qa-power8-5-kvm.qa.suse.de seemed to be stable and only showed the problem a
bit later. Now a 3rd machine shows the problem. Maybe the workload has changed.
(I'll investigate that.)
