Okay, the faulting instruction is the following: c0383360: 0f 1f 40 00 nopl 0x0(%eax)The Crusoe code morphing software apparently doesn't recognize these "long noops", and (presumably) the rest of the hinting NOOP group. gcc didn't use to generate them, and Crusoe/Efficeon generally do not benefit from code alignment anyway. I suspect the best thing to do is to use either a 586 kernel or build a dedicated Crusoe kernel without code alignment.
