I get the following error messages when trying to open a CD device
(specifically, the Teac CD-ROM CD-224E) that has no media present:
hda: packet command error: status=0x51 { DriveReady SeekComplete Error }
hda: packet command error: error=0x54 { AbortedCommand
LastFailedSense=0x05 }
ide: failed
The system can panic with a null pointer dereference using ide-scsi if
PIO is being done on scatter gather pages that are in high memory,
because page_address() returns 0. We are actually seeing this using a
tape drive. This patch will kmap_atomic() the pages before performing
PIO.

There's still a problem here, you are not initializing nsectors

I'd recommend applying this patch if nobody sees any problems with it.

If there is a bug, it is in ide_cdrom_driver declaration.
.end_request is not set to ide_cdrom_error.
I wondered about that. I'll give that a try.
OK, 2.6.11-rc3 has the same issue. The function ide_atapi_error() is
calling
drive-driver-end_request() when rq-errors exceeds ERROR_MAX,
