I'm using the aic7xxx controller. (With both, the old and
the new one I can reproduce the crash).
Alan Cox reports that the -ac kernels behave. This
makes me believe that the BUG sneaked into the linus
kernel at 2.4.10, where heavy block layer changes
happened, which were not applied to alan's kernel.
linus-2.4.0 behaves, too.
Here is
1) register dump
2) stack chain
3) last few lines dumped from syslog buffer
Is there anything more I can do?

Ralf
