Occasional System Lockups

Every couple of days, one of my Dell Work-Stations running freebsd 6.1 simply
locks up. The box can be pinged only IE there are no services running, locked
up screen/kbd/mouse. No caps-lock light action on kybd... On/OFF time.
Actually OFF doesn't work either (It's a dell, with ACPI power switch) only
hitting the reset button will revive things.
Machine restarts OK, complains about improperly dismounted drives.... etc.
There is no core file, and the last entries in messages just before the lockup
always look like this:
Aug 23 00:23:02 viola kernel: acd0: WARNING - PREVENT_ALLOW read data overrun
18>0
Aug 23 00:24:02 viola kernel: acd0: WARNING - PREVENT_ALLOW read data overrun
18>0
Aug 23 00:26:02 viola kernel: acd0: WARNING - READ_TOC read data overrun 18>12
Aug 23 00:28:32 viola kernel: acd0: WARNING - PREVENT_ALLOW read data overrun
18>0
There was NO CD in the cdrom drive either,
This has happened with the original GENERIC kernel, and also with the custom
kernel I recently built for that hardware.

The crash happens at intervals of between 1 and 3 days (the machine is never
turned off)
Any ideas where to start poking at this problem?
