I am test-qualifying this system for a few weeks now, and that bug only happened under very high load, apparently. So far no data corruption (data comparison is part of the test). > For debugging, it would help to have a reliable trigger, like "happens > every time I run smartctl manually" or "every time I do it while > 'cat /dev/sdc >/dev/null'" or at least "often while <some workload>".
