The exception comes from PMON too - Did you look up the EPC in your
System.map file ?

The kernel seems to be initializing and steps upon an virtual address
and triggers an TLB exception which as the kernel is not yet ready
to handle it itself, thus PMONs exception handler gets triggered.

My first guess is that you are catching a NULL Pointer exception
somewhere.
