It seems to be stable for a longer period, but it has borked out now.
As stated the issue seems way more frequent (if not only occuring) when
using md raid (and from what I saw from posts also when using xfs).
The array here has failed now with these messages:

The last part about attaching the device repeats a lot. The disk is accessible
now though (w/o reboot), so could probably just re-add it to the array.
To be sure I have stopped the array for now and am running badblocks
-svw against the disks on the mvsas controller. This has been running
for about 12 hours now without any errors in the logs.
