Well, your right as usual about my understanding. What I can't get my mind around is the fact that the mce(s) go away as long as the driver isn't loaded. ...
The driver tells the hardware, among other things, where to transfer data via DMA. Such transfers are done asynchronously and if the driver gives bad addresses or transfer sizes to such a DMA-equipped card, then that card's actions (carrying out the driver's instructions) can cause "hardware" errors.
I don't think that will trigger an MCE though
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.
