 One of the less endearing properties of mips is that all-bits-0 is a
 nop, so if you jump off the deep end you're likely to keep executing
 until you run into something unrelated.
 
 Can you look at the kernel from this (e.g. with nm -n) and check where
 the address 0x(80)2b7400 is relative to its .etext, .end, etc.?
 
 It's suspicious that it's round like that, and yet it's not a page
 boundary.
