Hi, I'm trying to boot a Sun Ultra 2 with netbsd-current.  The machine
runs file on 1 CPU but when i try to boot a MP kernel, it panics..

cpu0: booting secondary processors:
mp_tramp: 0xfff6a000
cpu1 fired up.
cpu1 now spinning idle (waited 2 iterations)
cpu1 enters idle loop.
<SNIP>

then it's either ...

trap type 0x10: pc=3D8 npc=3Dc pstate=3D820006<PRIV,IE>
kernel trap 10: illegal instruction
cpu0 paused.
Stopped in pid 1.1 (init) at

or

data fault: pc=3D100a480 addr=3D2c420000000
kernel trap 30: data access exception
cpu0 paused.
Stopped in pid 4.1 (pagedaemon) at      netbsd:cpu_switch+0x15c:        stx
        %
l1, [%l6 + 0x10]
db{1}>

Any ideas or thoughts as to why this is happening would be much appreciated=
..
Below is the output from banner and the initial boot process
