This looks similar to a problem I've been having with mpt2sas (in several machines with various LSI controller cards). In my case the crashes went away when I disabled hddtemp and smartd (and avoid doing smartctl or hdparm when there's activity on the disks). With hddtemp running mpt2sas would crash every time within 24 hours of boot, sooner if there was heavy disk activity; with sufficiently heavy disk action a single smartctl -a could crash it. After disabling hddtemp, no problems. So it would appear there's a bug in mpt2sas command passthru handling. I don't know if this is a different bug, but if hddtemp or smartd are running, it might be worthwhile to try disabling them.
