Duh? Bad things happening in the NCR driver
The machine continued to run, but I later found out that some
filesystems got corrupted in the process.
My SCSI chain is:
scsi-ncr53c7,8xx : at PCI bus 0, device 6, function 0
scsi-ncr53c7,8xx : NCR53c810 at memory 0x4200000, io 0x8000, irq 11
scsi0 : burst length 2
scsi0 : reset ccf to 3 from 0
scsi0 : NCR code relocated to 0x4053c6b4 (virt 0xfffffc000053c6b4)
scsi0 : test 1 started
scsi0 : NCR53c{7,8}xx (rel 17)

The machine is running Linux 2.1.103.
Hope this helps somewhat. Let me know if I can provide more details.
