Random reset in Nios II

Thanks. I actually have an instruction related event.

I added an alt_instruction_exception_register(InstructionException), and some code to allow me to cause an instruction exception when I want to.

My handler does trap my intentional unimplimented instruction but it is also getting traps every second or so from a location in

tcp_wakeup(void * event) PC=105a4f8, addr = 0, inst = 24000117, cause = -1 the instruction is

/* use extension */

WEP =tcb->OSTCBExtPtr;

105a4f8: 24000117 ldw r16,4(r4)
