panic at boot on 4/200

[foo bar <tokenalt%gmail.com@localhost>]

Hello all

I have recently gotten my 3200 & 4200 CPU boards working in a 4/110
case and while the 3200 works fine the 4200 does not. The kernel I'm
booting on the 4200 will boot fine on a 4300 but on the 4200 it panics
with mutex errors. I don't know if this is bad hardware or if there's
something different between the two CPU boards. Unfortunately the
ethernet does not work on the 4200 board so testing new kernels is
slow.

Sun Workstation, Model Sun-4/200 Series.
ROM Rev 1.7, 32MB memory installed, Serial #4086.
Ethernet address 8:0:20:0:F1:50.
