Howdy kernel folk,
I'm working on a kext and have managed to code myself into causing a
Machine Check Exception. Fun. :-)
Stack traces are meaningless so I am trying to work out the possible
causes of an MCE from my code.
I'm pretty certain at one cause of an MCE is stack overflow. That's the
first place I am looking. I have some code that is likely accidentally
being called endlessly recursively (oops :-). (I fully understand the
recursive problem, it's just a matter of finding the offending callers.)
What are the other potential causes of an MCE?
(Note: this is _not_ a hardware problem. My code is clearly causing the
problem.)
Thanks for the tips,
...Duane
