Re: system hangs ... not sure how to debug ...
well, John just gave a good break down on what needs to be done to debug
it ... do you have easy access to a serial console? I'm trying to
scrounge up hardware at this end to do it with, but its difficult :)

Marc, I noticed you tried the BREAK_TO_DEBUGGER and whatnot already, perhaps letting us know what hardware you have in your smp box might help some, I'm running SMP and doing buildworlds and kernel compiles without a problem. I'm not however, running X nor doing any desktop work on it. I think I also figured out what makes the box so damn sluggish when doing lots of IO *bops dillon* :) -- -Alfred Perlstein - [[EMAIL PROTECTED]|[EMAIL PROTECTED]] "I have the heart of a child; I keep it in a jar on my desk."

system hangs ... not sure how to debug ...
Morning all ...
Every since the SMPng code went into -current way back when, I've
been experiencing hangs ... and am not quite sure how to debug this. I'm
in X all the time, so breaking to the debugger to see where its hanging
isn't possible ...
Some kernels its relatively easy to trigger, some kernels are
harder to trigger, but they all do at some point in time ...
Can someone suggestion a method of being able to debug this?
thanks ...
