2.4.20pre7, aic7xxx-6.2.8: Panic: HOST_MSG_LOOP with invalid SCB 0

Celeron 1.3GHz, Intel i815 chipset, 512MB ram.

AIC-2640 PCI card with uw and narrow connectors. A Seagate scsi disk
(rootfs) attached to uw, and a HP tape drive attached to narrow. Tape drive
never used.

I only ran 2.4.20pre7 (no other patches) for a night and it crashed:

been changed since, though).
