I don't believe this has anything to do with the io scheduler, it looks
clearly like a problem deep inside the aac driver (and thus completely
io scheduler independent). The fact that it triggers with deadline is
likely completely coincidental.

Looks like scsicmd->scsi_done == NULL which is very odd. You may want to
try and add some debug prints checking that (and dumping scsicmd state)
fact.
