Well, in this case, it's probably the DEBUG_PAGEALLOC that Michal has
enabled, which causes a page fault - and then a triple fault - at
secondary CPU startup. And the triple fault then results in a reboot.
Which explains the symptoms he gets.
Without DEBUG_PAGEALLOC it ends up being "just" a single-bit corruption, yes.
