What could be causing unexpected reads to acd0?
I'm seeing this sometimes before my machine dies:

6.4-PRELEASE sporadically panicking with fatal trap 12
...EST_UNIT_READY read data overrun 18>0
kernel trap 12 with interrupts disabled
I don't have atapicam built in the kernel and it wasn't loaded, and I'm pretty sure no media was inserted in my dvdrw unit since the last boot.
The other report has a similar message too (acd1: WARNING - READ_TOC read data overrun 18>12)
Here's the backtrace:
