I just tried 2.1.65 and got an error I have not seen before:
scsi0: unexpected interrupt.
As the (edited) dmesg dump below shows, this occurs while trying
to scan the SCSI bus for devices. I have a hard drive, CD-ROM,
floppy drive and tape drive on it, and they work fine in 2.0.21.
If this is a known bug, I would appreciate a quick "known problem,
upgrade to Ver 2.1.##".
If it is not a known bug, I can provide more information on
request.
