[Mactel-linux-users] CDROM trouble

[Reinier L. <rei...@ph...>]

Hi Mactelists,

On my new MacBook, the CD-ROM drive made the kernel say some weird messages:
When I ran lilo (which acts on the hard disk, /dev/sda, actually):
hda: packet command error: status=0x51 { DriveReady SeekComplete Error }
hda: packet command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown

and when I try to unload the ide_cd module, the module does not get unloaded, 
and the driver prints some identification string for the device ("hda: ATAPI 
24X DVD-ROM ...")

Also, randomly I get kernel error messages that say that the CD-ROM "appears 
confused".

I took this all for granted, but now I try to make suspend-to-RAM work, it 
seems the suspending process hangs in the suspend function of the CD 
driver "ide-cdrom". Suspending to disk does work.

I'll dig on into the cd driver as long as I've got nothing better to do, but 
any hints are appreciated.

Regards,
Reinier
