And then it crashes. The way it crashes appears random. Either a reboot 
or a red stack trace for an exception varying from "Division by Zero" 
via "Invalid Opcode" to "Page-Fault Exception". If there are any 
readable label in the trace, it's this:

	AslInformation+0000F1h
	DxeCore+032040h

or
	PeiCore+86190BDh

But most times it's just

	No Image Information

Would it help if I gather more accurate statistics on these traces?
