	Mounting an unconfigured device (e. g. /dev/scd0a, /dev/wcd0a,
	/dev/wfd0a) causes a panic.

	hal ROOT dirk 1004 (~): mount /dev/wfd0a /mnt

 Could you send us the kernel configuration file for this machine? I
 cannot reproduce the problem on neither 3.0-RELEASE as on 4.0-CURRENT
 (with cut&paste nor other devices).
 
 Does the problem still occur?

 Can't reproduce the problem, too. I tested it with 3.2-STABLE.
 It seems to be fixed, now.
