The kernel memory is unswappable so a PTE is always available. If the TLB refill handler cannot fetch it for some reason, then there is a bug somewhere. It might be helpful if you narrowed it down a bit -- refills work correctly for modules, including interrupt handlers, and they reside in KSEG2. -- + Maciej W.
