If it's a Perc3/Di it's a adaptec (aacraid) controller. Basically it is

There is a workaround which you can found on the just launched
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
I don't make sense, I don't pretend to either. Questions?
