>Environment:
Dual PII system with 2940UW SCSI.
  NTLoader and NT4 on target 0,
  BootEasy and FreeBSD on target 1.
Use SCSI BIOS config to select boot target.
>Description:
All attempts to boot kernels on sd1 (or sd1a or sd1s1a) cause the following panic:
	changing root device to sd0s1a
	error 22: panic: cannot mount route (2)

This includes GENERIC and SMP-GENERIC and minimal config
files (UP, SCSI, FFS only).

Attempts to use -a (ask) boot option also fails.  I assume this is
a related problem.

Problem also occurs when using Feb98 or Sept97 WC SNAPSHOTS.
>How-To-Repeat:
Use sysinstall to build system on sd1 and boot.
>Fix:
No known fix but can workaround problem as follows:

Retarget install drive to target 0.  Load system and boot.
Build new kernel with:
	config	kernel	root on sd0	# sd0 is second disk (target 1)
	controller	ahc0			# 7880/2940UW
	controller	scbus0 at ahc0
	disk		sd0	at scbus0 target 1 unit 0
	disk		sd1 at scbus0 target 0
	disk		sd2 at scbus0 target 4
	disk		sd3 at scbus0 target 5
	device		cd0 at scbus0 target 6

Edit /etc/fstab and MAKEDEV as necessary and reboot.
