Unfortunately since "trace/u" is not implemented in mips's ddb, it's making
this init problem hard to debug.  All I have to work with is the following:

PC 0x400180: not in kernel space
0+400180 (400180,c4705f68,0,0) ra 0 sz 0
User-level: pid 1

Could someone with a working NetBSD-1.5/arc install tell me where in init
that address is?  It's always sitting at that address...

Thanks,
