DVD drive not recognized

Hi all,

Thanks for the suggestions on the DVD drive. You were right. The kernel 
was being passed options in /etc/grub.conf, which was making it treat 
the DVD drive as a SCSI device (hda=ide-scsi). I removed these options 
and I was able to mount a CD on the drive. I haven't tried it with a DVD 
yet, but I think it should work.

However, there seems to be a new problem that I noticed in the logwatch 
for the machine. In the logwatch, I observed these three lines:

WARNING:  Kernel Errors Present
   hda: packet command error: error=0x54...:  1Time(s)
   hda: packet command error: status=0x51 { D...:  1Time(s)
   vesafb: probe of vesafb0 failed with error -6...:  1Time(s)

Since the errors mentioned hda, I assumed that it had something to do with the DVD drive.

I mounted a CD in the drive today, and did 'tail -f /var/log/messages'. The following showed up:

Aug 10 09:59:36 (machine-name) kernel: hda: packet command error: status=0x51 { DriveReady SeekComplete Error }
Aug 10 09:59:36 (machine-name) kernel: hda: packet command error: error=0x54

What seems to be the problem? The CD mounted properly, and I was able to 
read files on it.

I also seems to have some issues with sound on this machine. When the 
computer is shutting down, I see an error message saying that shutting 
down aumix failed. I have aumix-2.8-6.EL installed.

Thanks a lot for all your help again.

Saurabh.
