after upgrading the aacraid driver / kernel from aacraid 50792 to aacraid 50877.
The aacraid driver version was updated to 50792 in commit 0662cc968ace ("scsi: aacraid: Update driver version") and to 50877 in commit 1cdb74b80f93 ("scsi: aacraid: Update driver version to 50877"). That means that the regression you encountered got introduced after commit 0662cc968ace. 114 changes got checked in after that commit. That's too much to find the root cause by rereading all these changes. Is there any way to trigger the problem faster such that it becomes feasible to run a bisect?
$ git log 0662cc968ace..master drivers/scsi/aacraid | grep -c ^commit 114 Bart.
