As everybody probably knows by now (:-)) I've got an ASUS PVI-486 SP3
motherboard with their SP-200 PCI SCSI controller, based on the NCR
53c810 chip. Attached to this I've a 350 MB Quantum Lightning drive
and a Sony CD-55S CD-ROM. I'm running the generic NetBSD 1.0 kernel
and I've just discovered some pretty bad problems that pop up when
I access my CD-ROM.
So long as I don't use the CD-ROM too heavily, things seem to be all
right. However, copying a large file or three will often start this
error, and doing a _du_ from the root of the mounted CD-ROM will
guarantee the error. I first get
ncr0 targ 3?: ERROR (81:50:a7) (e0/13) @ (2577f0:48000000).
ncr0 targ 3?: ERROR (81:4:a7) (e0/13) @ (2577f0:48000000).
and the disk light just stays lit. Then I see
ncr0: timeout ccb=f8667600 (skip)
about every thirty seconds or so. The only real option at this point
seems to be to reboot; the system never comes back, it just keeps
printing that last message. I've tried a different SCSI cable and a
different terminator, but the problem persists.
Has the NCR code changed in the more recent kernels? Should I try an
upgrade to fix the problem?
For reference, here are the boot messages:
