If it's a Perc3/Di it's a adaptec (aacraid) controller. Basically it is crap piece of hardware that falls apart under load.
There is a workaround which you can found on the just launched http://linux.dell.com/
The scsi layer in the Perc3 gets stuck often which results in the controller firmware deadlocking. Upping a certain timeout in the driver to 60 seconds will prevent this from throwing a IO error to the kernel but the box will stall for a seemingly long time.
The best workaround for the moment is using either software raid or purchasing a Perc3/DC or better yet a Perc4/DC.
Both are also faster and a lot faster respectively with regards to raid 5 throughput.
