Re: NetBSD 5.0.2 can't handle 7455 CPU @ 1 GHz?



That's hard to say.  I smell a race, but I do not have enough data to say
where that race might be.

The machine simply hangs up hard.  What would I have to do to
get said stack trace?  My tool of choice in debugging the kernel
is the "printf" - not so useful in this case.....
