Subject: [PATCH 0/2] fix race conditions in SCSI/Block leading to oops
Date: Fri, 22 Apr 2011 10:37:18 -0500 [thread overview]
Message-ID: <1303486638.2590.21.camel@mulgrave.site> (raw)
There's a lkml thread on this:
http://marc.info/?t=130253369300004
But the synopsis is that some combination of delaying factors in the
boot of this machine exposed a race in SCSI and block between teardown
and reuse of SCSI devices. This two set series fixes the race.
