S:M:27417:288306 is a new kernel that was pushed in the queue on the 16th. Seems like the culprit to me.

As we can see from https://openqa.suse.de/tests/10331350#step/syscall_thrasher/1, removing the 27417 repos and reverting to the older kernel (5.14.21-150400.24.38) fixes the issue.

seems like it is a regression, we (Marcus, Fabian and I) are looking into it.

The issue was not related to a regression, but to slowness in openqa. By redirecting to a file instead of to video, the test runs in 5m instead of 18m.
I've also added the code to upload the output to openqa, so that something should happen we can always debug it.
