Ok, so.. the IDT doesn't get messed up, I think that can be safely

It kind of puzzles me what's going then.

The only reason I know for a CPU reset is a triple fault. Which occurs
if a trap occurs while handling a trap, and then the double fault
can't be handled either.

Usually this is a sign of a messed up stack or IDT (both things the
CPU accesses when it handles a trap). But, this doesn't seem to be
the case.

I wonder what it is.. maybe the GDT. Or something outside the CPU
