oops in ide-scsi emulation

I got the following oops while trying to burn a CD-RW, using
kernel 2.4.9
cdrecord 1.9
HP CD-writer plus, 7200i (an IDE unit)
An intel celeron A 300MHz

The ide-interface as reported by lspci:
00:07.1 IDE interface: Intel Corporation 82371AB PIIX4 IDE (rev 01)

CD-burning worked fine under kernel 2.2.14, but has not worked with
kernel 2.4.x. This time the computer crashed after it had burned approx.
4 MB.

I copied the oops from the screen by hand, but I have checked it
carefully, so I believe it is correct.
If I need to tell you anything more, please ask.

ksymoops 0.7c on i686 2.4.9. Options used
     -v /usr/src/linux/vmlinux (specified)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.9/ (default)
     -m /usr/src/linux/System.map (default)
