After trying a few "suspect" hunks of the git-scsi-misc.patch, I have verified that the commit 8655a546c83fc43f0a73416bbd126d02de7ad6c0--as discussed in http://marc.info/?t=119689824100001&r=1&w=4 for a different symptom--seems to be the culprit. Reverting this patch allows me to boot with async scsi scan enabled. I'm starting a stress test to verify that this fixes the "disk going off-line" issue that I saw earlier.
