then I can't help, sorry
better wait for someone who knows anything about ATAPI

I'd try to mess around with PIO/WDMA/UDMA modes as well, and also try
dumping data directly (i.e., `dd if=/dev/[a]cd0 bs=2k` for a data cd),
attempting to read & record (both with cdrecord and burncd) cd and dvd,
enabling verbose output in kernel for ata & SCSI wherever possible,
and, well, facing the panic armed with a kernel debugger. Anything to
get a hint at what's going on. Does it play audio CDs?

Chances are, you have a drive with broken firmware. As a last resort,
I'd try flashing it with compatible firmware. Look through e.g.

But remember: last resort.
