2.4.20 Kernel panic in IDE-SCSI with CDROM drive

I recieved the appened kernel oops while attempting to mount a cdrom, as well
as to dd the CDROM into a file. This as occured under 2.4.19 as well as
2.4.20 (reason why I tried upgrading). The drive is bootable and works fine
under Win98.

The oops in question locks the system up completely and causes Caps+Scroll
lock lights to blink.

The drive in question is an HP CD-RW drive, attached via IDE using IDE-SCSI.
I have also attached information on my drive, should it be useful.

Thank you for all of yuor hard work. Let me know if you need more info.
