>Description:

You can not configure a device on the second bus of a multiple bus
adapter.  scsiconf uses a "key" of (host adapter, unit) to tell
what belongs on a given bus, and if the device on the second bus
collides with a device on the first bus the device slot allocation
will fail and the system will panic during boot.

>How-To-Repeat:

Try to configure a device on the second bus that collides with something
on the first bus and boot.

>Fix:

Work around:
Don't try to configure the devices, but live with the "autocounting"
devices;

Real fix:
Modify config to support a new keyword so that you can do things like:

controller scbus0 at aic0 bus 0
controller scbus2 at ahc0 bus 1

and modify scsiconf to use (host adapter, unit, bus) as the key.
