I'm seeing this sometimes before my machine dies:

Oct 26 03:28:00 belle kernel: acd0: WARNING - READ_TOC taskqueue timeout - completing request directly
Oct 26 03:28:00 belle kernel: acd0: WARNING - READ_TOC freeing taskqueue zombie request
Oct 26 03:30:00 belle kernel: acd0: WARNING - READ_TOC taskqueue timeout - completing request directly
Oct 26 03:30:00 belle kernel: acd0: WARNING - READ_TOC freeing taskqueue zombie request
Oct 26 03:32:00 belle kernel: acd0: WARNING - READ_CAPACITY taskqueue timeout - completing request directly
Oct 26 03:32:00 belle kernel: acd0: WARNING - READ_CAPACITY freeing taskqueue zombie request

I run the gnome desktop environment.  Could it be that?

I do not have this mounted.  The only thing that's running around this time
is /sbin/dump.  I'm never at the machine when this happens.
