After they ran for half an hour I find these in /var/log/messages:

Apr 15 11:03:54 hurz kernel: nvme2: Missing interrupt
Apr 15 11:07:07 hurz kernel: nvme3: Missing interrupt
Apr 15 11:09:47 hurz kernel: nvme4: Missing interrupt

They are the only occurrences. The system does not seem to hang or otherwise
misbehave ...
