Panic in "irq15: ata1" (perhaps just ATAPICAM...?)

Okay, I can't exactly reproduce the orignal panic (I think -- these might
all be related), but here's another cdparanoia panic. I am using ATAPICAM,
which I vaguely remember has caused some issues with other people. Note
that this ocurred after I let bgfsck run its course.
First off, a 'dmesg | grep ata1':
ata1: at 0x170 irq 15 on atapci0
acd0: CDRW <SONY CD-RW CRX230E> at ata1-master PIO4
acd1: DVDROM <Pioneer DVD-ROM ATAPIModel DVD-120S> at ata1-slave PIO4
cd0 at ata1 bus 0 target 0 lun 0
cd1 at ata1 bus 0 target 1 lun 0
Now the actual panic:
Fatal trap 12: page fault while in kernel mode
cpuod = 0; apic id = 00
fault virtual address = 0xc1cad220
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc049a4a9
stack pointer = 0x10:0xd42bac74
frame pointer = 0x10:0xd42baca8
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 26 (irq15: ata1)
kernel: type 12 trap, code=0

Me being a n00b, I have no idea what's going on. But I /do/ know that I can
reliably produce a panic while ripping this CD.
