Can you enable 'TRAP_DEBUG' in sys/mips/mips/trap.c and see if you can get the trap information printed. Adding a line #define TRAP_DEBUG after all the #includes in trap.c should do it. This should print the pc, ra, and badvaddr which would help a lot in debugging. In the meantime I will look at the code again and see if I can find anything obviously wrong. Thanks, JC.
