At this point I suspect one of these two changes caused the regression, as I suspected initially:
scsi_dh: fix reference counting in scsi_dh_activate error path
put stricter guards on queue dead checks
although 2.6.38.8 has a fix for the second one, testing on comment #10 showed no good results for it.
Lets finish bisect at least, to confirm what change brought the problem:
# good: [a29ae2d0b5e069c4226b69a70d70198d809a6489] mpt2sas: prevent heap overflows and unchecked reads
git bisect good a29ae2d0b5e069c4226b69a70d70198d809a6489
Bisecting: 2 revisions left to test after this (roughly 2 steps)
