i did compile kernels under 1.0 and 1.1

now trying to compile current kernel on a NetBSD/i386 1.2
i get to the debugger after swapgeneric.c, it says:

NMI ... going to debugger
kernel: type 265 trap, code=0
Stopped at      0x9189: jbe    0x9190

can anyone give me any clue in what's wrong??
(i did build the new config)

i'm doing this on a 486 with 16Mb
purpose is to swap inn from a mac68k to a i386.
second purpose is to get a ethercard working on a not supported irq.

ThanX,
