I would need to see the 5 lines prior to this message. I can not determine
why it failed just from the above message.

What may be happening here is the drive is not reseting properly (happens
with some drive/power pack combinations if the power pack is turned on
while plugged into the drive). The parallel <=> SCSI interface is
functioning fine but it can not find any device on the SCSI bus, hence the
driver aborts.

If the above occurs again, immediately try to insert a disk. If the disk
goes in without the orange status LED flashing then you have a hung drive.
Just pull the power connector out and insert.

kerneld (or modprobe) can not locate the SCSI disk module which is
responsible for block-major-8. You may need a new version of module utils
OR check the config file for kerneld.

Just when you thought you have seen every possible
parallel port chipset there is, some manufacturer comes
out with a new quirk. Just to make things worse, every
mainboard manufacturer on the planet decides to use it.
