>Description:
I had a panic this morning during raid autoconfiguration.
cd1 contained an audio CD.
Everything looked fine, until (hand-copied):
cd1: (ahc0:0:6:0): Check Condition on CDB: 0x08 00 00 00 01 00
	SENSE KEY: Illegal Request
	ASC/ASCQ:  Illegal Mode For This Track
cd1: dk_busy < 0
panic: disk_unbusy

The output of tr/u:
cpu_Debugger
panic
disk_unbusy
cdstart
cdstrategy
readdisklabel
cdgetdisklabel
cdopen
spec_open
VOP_OPEN
rf_find_raid_components
raidattach
main

Kernel and core dump available on request, until I run out of space and
delete the core dump [I'll keep them for at least a week].

I wonder why raid autoconfig is even looking at my cd drives...
>How-To-Repeat:
Boot with audio cd in cd drive and RAID_AUTOCONFIG in kernel, I presume.
I haven't tried to reproduce it though.
>Fix:
Unknown.
