I'm getting a repeatable panic when try to access my cdrom drive. -CURRENT as
of yesterday. I seem to get this when I try to mount my cdrom drive a second
time.
I seem to get these error sometimes when trying to mount a cd for the first
time and it doesn't end up work, and the second time I get the panic.
