Perhaps someone on this list can shed some light on a problem I'm having.
I have a PPro-200 system running 2.2.6-STABLE. The system was last build on
the morning of April 18th. I have a generic NCR PCI SCSI card with a Toshiba
XM-6201TA 1030 hanging off of it. I am reasonably certain that it is
terminated correctly.
The setup ran perfectly until last night. I woke up this morning and discovered
that my power supply had died. I replaced it, crossed my fingers, and rebooted
the system. Everything seems to work fine with the single exception of the
Toshiba CDROM drive. I am seeing the following messages at boot time.

I can mount and access CDROMs, but every time I do, I get the following
string of messages on the console.

-------------------------------------------------------------------------------
Any clues here? Should I suspect the SCSI controller or the Toshiba drive?
I've resisted the urge to cvsup and remake the world. I'd rather attempt to
find some answers first.
Thanks in advance for any assistance,
