I just installed a new kernel and updated my packages. After I did that I loaded the lilo configuration and got this error

ide-scsi: hda: unsupported command in request queue (0)
end_request: I/O error, dev 03:00 (hda), sector 0

I am new to linux and I don't understand what the problem is. I have tried google groups with little success

cat lilo.conf is:

prompt

Any help would be greatly appreciated

Just comment out the append="hda=ide-scsi" part. There's no need for it with the new 2.6 kernels.
