knoppix 9/5/03 : dmesg messed up

Hi;

I installed knoppix 9/5/03 onto my box.

When I type dmesg as root at a command prompt I got:

------------------------------------------------------------
ide-scsi: hdc: unsupported command in request queue (0)
end_request: I/O error, dev 16:00 (hdc), sector 1030
-------------------------------------------------------------

over and over again.

I have been using various versions of knoppix ( hdd install ) since march and have never had this problem.

Anyone have any idea whats wrong and how I can fix it?

Steve
