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. 
acd0: FAILURE - READ_CD status=51<READY,DSC,ERROR> sensekey=MEDIUM ERROR
