No problems here with SMP P3 machines, with software RAID and Adaptec 2940 
cards. I'd concur with the others that it's most likely the RAID cards, 
some driver/firmware conflict.

Can you (using top or whatever) tie the high loads to certain processes? 
That might give further indication of what the cause of the problems is.
