Strange - definitely, strange. Of course you're correct about memory errors
going undetected on standard PC hardware, and usually these undetected
errors lead to other failures later on:

You get SIG11 errors when running programs(kernel compile seems to be agood
example), you get crashing processes, you get all sorts of weird funnies but
you really shouldn't get machine check exceptions.

I don't think there is a way a machine check exception can be triggered by
software - which it would have to be in order to be caused by bad RAMs.

Bye, Martin
