Curious... I had a similar fault on 2.1.51, and I reported it to this
a couple of weeks ago. My card is a PCI one, and always worked perfectly
to 2.1.42.

It turned out that I had some remains from old patches, and I had to
from a clean kernel tree. So I tried 2.1.53 with all secondary aic7xxx
options ON, and got two complete system locks while accessing the SCSI
Hopefully no file was lost.

I recompiled the kernel with all secondary options OFF, and I had no
problems since then.

I have not followed the 2.0.31 development, but my feeling is that now
aic driver is the same for 2.0 and 2.1 kernels. Right?
