Well, one thing that can happen is that interrupt vectors can be clobbered by DMA activity, after which it can become impossible for the processor to continue because it gets a fault trying to execute from bad addresses or from valid addresses that contain gibberish instructions.
Well, it's obviously possible for software to hang a CPU, that's not in question.
But I still don't think it will trigger a machine check exception. That's not the type of errors those are designed to alert about
How does the CPU respond to a fault that occurs when it's processing a fault? Isn't that one of the things that machine-checks report?
I don't think so http://en.wikipedia.org/wiki/Machine_Check_Exception We're talking about exclusively real hardware problems Anders -- Madness takes its toll -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
