>Release:        FreeBSD 3.0-CURRENT i386
>Environment:

	Kernel config file, that worked for ages, with some SCSI
	disks "wired down".
	
>Description:

	I had several of my disks "wired down" in the config file
	as
		controller scbus0 at ahc0 bus 0
		disk sd0 at scbus0 target 1
		disk sd1 at scbus0 target 2

	After the introduction of CAM, this silently produces
	unbootable kernel -- "can not mount root (2)" panic.

>How-To-Repeat:

	See above.

>Fix:
	
	s/sd/da/ , but one would expect sd to continue working, or,
	at least, config to complain!
