Hi;
This happens just before the scsi cdrom would be detected
during boot. The bad: part and the call trace are endlessly
emited (exact same trace) and its pretty much game over.
(fortunately I had a serial console machine handy.)
The driver is compiled into the kernel, not a module.
The card (pas16) works under 2.4. I can test things
or supply more information/debugging if anyone wants.
Thanks;
Paul

Im using generic 5380 on 2.5.x but not 2.5.50 yet. Can you turn on all
the NCR5380 debugging and see where it errors from (the trace doesnt
give an answer as gcc has been smartly inlining functions used in one
place only I suspect)
