98% certainty it is a memory (UPM) problem. You are probably randomly misreading an instruction as 0xFFxxxxxx which is a floating point instruction. This causes a FP emulation trap. If you look at where the trap occurred (SPR register SRR0) and look at the actual memory location in question with your debugger, you probably will not find a FP instruction in memory, which means it was misread.
