Nothing much to report except that it happens for me, too, whether it's
with the regular acd(4) device or the ATAPI-CAM cd(4) device. It seems
like it's a not a hardware issue. The process in the ata/acd/atapicam
drivers dealing with detachment might be particularly messy. These
lock-ups in general are almost as annoying as the ones that various
people (myself included) are having from during the boot process. If
you have a serial console, it would be worth seeing if it can respond
that way.
