Comment # 3 on bug 1177595 from Peter van Hoof

I decided to use the time to test some other kernels. First I downloaded some
kernels from kernel.org: 4.19.151, 5.4.71, and 5.9.0 all showed the same
problems as described in my report. Kernel 4.14.201 did not boot.

I also reinstalled a kernel from openSUSE 15.1:
kernel-default-4.12.14-lp151.27.3. This one behaved differently. I started the
mdadm scrub at 19:08. There was one burst of messages from mpt3sas_cm0 at
01:27, followed by a single reset of sde and another burst of messages from
mpt3sas_cm0 at 06:39, followed by a single reset of sdc. The scrub ended
successfully at 13:27. So the differences are that the error messages and
device resets started much later and were far, far less frequent than with the
later kernels. There were no I/O errors reported. In my initial report I
thought that openSUSE 15.1 kernels would be free of these errors. I cannot
confirm that, but the problems are clearly far less severe with the 15.1
kernels. Since mdcheck only runs for 6 hours on a single day, the system may
never or rarely have reached the point were these messages were triggered...
