 The lack of information provided makes it difficult to figure out who
 should look at this.  Could show us your dmesg output and tell us which
 device you used to mount the CD-R?
 
 Ciao,
 Sheldon.

 Sheldon, here's what I see:
 
 hbo# mount /dev/acd0c /cdrom
 acd0: READ_TOC - ILLEGAL REQUEST asc=24 ascq=00 error=04
 panic: vm_fault: fault on nofault entry, addr: c685800
 Debugger("panic")
 Stopped at	Debugger+0x36:	mov $0,in_Debugger.322
 
 Please let me know if you need any other information.
 
 Lars
