In the debugger, if you could get a stack trace with the 'trace'
command that would be helpful.  

What's happening here is an unaligned address access.  'lhu' is a
16-bit load and the address used, 0xc001622f, is on an odd byte boundary
which is perfectly legal on processors like the x86 family, but not ok
on the mips.
