Curious... I had a similar fault on 2.1.51, and I reported it to this
list
a couple of weeks ago. My card is a PCI one, and always worked perfectly
up
to 2.1.42.
It turned out that I had some remains from old patches, and I had to
restart
from a clean kernel tree. So I tried 2.1.53 with all secondary aic7xxx
config
options ON, and got two complete system locks while accessing the SCSI
disk.
Hopefully no file was lost.
I recompiled the kernel with all secondary options OFF, and I had no
more
problems since then.
I have not followed the 2.0.31 development, but my feeling is that now
the
aic driver is the same for 2.0 and 2.1 kernels. Right?
