Also see my comments on #125213 about those two workers. Unfortunately the crash dump wasn't there anymore when I had a look. So I'm not only wondering why it crashed but also:

• Why was the crash dump removed?
• Is it related to the crash of #125207 which showed the exact same symptom (except the critical warning from smart)?

Note that the problematic SSD is nvme0n1 which is not the drive where the root filesystem is installed. So I wouldn't expect a kernel panic just from that (only /var/lib/openqa is on that SSD).

I moved crashdump to my home -> to be albe start service, but still we have it..

Both crashes were in time of btrfs maintenance.. and yes, I don't think nvme problems are related to crash.
