We have had reports of driver stalls on AACRAID drivers under high load. This seems to be related to the ammount of concurrent IO that can be pushed to the controller. Reducing the maximum queue count for this driver sorts this out. For further details see the upstream and Ubuntu bugs:
http://bugzilla.kernel.org/show_bug.cgi?id=11120 http://bugs.launchpad.net/bugs/249964
Following this email is a patch from Mathias Urlichs to reduce the queue size. This has been tested and confirmed to fix the issue by a couple of those affected.
Patches against Linus' tree.
