I'm working on a kernel for the mvme88k. I'm running into some problems
with the autoconfig process. I know this is very machine dependant, but
maybe someone has had a similar problem on another arch.
kernel autoconfigs the cl device,
then the siop device,
then bombs with an exception before the scsibus is configured.
The exception number is 0 (zero). Looking through the code I find that this
exception occours when there is a non-trap exception and shadowing registers
I can get the exception at another point by specifying -d kernel param.
As soon as Debugger( ) is called from consinit( ), BOMB!
