If you try to submit an error report to kernel guys and they see you're using a "tainted" kernel, they won't help you. This is not the case with the unRaid kernel build. As for the stall.. I have not reproduced this yet. The message is "informational" meaning there's not anything crashing, but still should not happen and I'll get to this issue at some point.
June 17, 201313 yr I would get a lot of these CPU stall errors when running a parity check and the value of md_sync_window seemed to have some effect as to the frequency of the errors occurring. I did not get any CPU stall errors on RC15 when I ran a non-correcting parity check.
June 17, 201313 yr Just installed RC15 an running a parity check now. Some time after starting the parity check these messages start appearing in my syslog.
