I have an IBM serveraid 8k which is currently running a 2.6.32 kernel. I tried booting knoppix 6.4.4 which uses a 2.6.37 kernel to do some disk rearanging and was rather surprised that the aacraid failed to come up and instead resulting in the message:
AAC0: adapter kernel panic'd ffffffff (transcribed by hand from memory, but I am pretty sure they were all f's).
The firmware version on the adapter is 5.2-0[16002].
It is running a single raid5 across four 750GB SATA drives (total of 2.25TB capacity, which has turned out to be a huge pain in the ass, but that's hopefully an unrelated story).
I would love to know why it works fine with 2.6.32 but fails completely with 2.6.37. I can't find any commits in git that seem major enough to really affect things, but clearly something did. I am somewhat worried my next kernel upgrade won't go well.
