This should have been fixed a while ago by jylefort when he set the
default device for ATAPI access to be the ATAPICAM device (as opposed to
the ATA device).  Assuming you have not undone that change, and are
running the latest version of HAL, these panics should not be occurring.

Even still, you're right that these are not HAL bugs, but rather an
issue in the kernel.  I use nautilus-cd-burner to burn CDs in GNOME, and
I have never had such a panic on 6-STABLE.  n-c-b uses cdrecord, cdrao,
and dvd-utils under the covers to do the actual device work.  Not sure
what k3b is using, but maybe it diddles something it shouldn't.
