Then it seems that you don't have a hardware problem but a software
problem; i always try to rule out any hardware problems first. That
includes a memory test (like memtest86). It's all too frustrating trying
to isolate a bug which eventually was hardware-related.

But it seems you have a driver problem indeed. All i can say is that i
have no problems with my onboard Promise controller; although its not
processing terribly much data. A different controller and/or software
RAID might be a solution/workaround.
