I won't be surprised if it's a hardware related problem.
Do you know which is the real manufacturer of the RAID controller and
firmware ? I don't think Transtec make their own system...
IMHO, you should try big bench without DRDB using I/O benchmark tool and
also simply dd to make big parallel transfers and check if you can
reproduce the bug. It would be interested, if you get the bug, to try
with other linux kernel revision and also other OS...
Good luck!
