Somehow it is trying to execute code in the middle of an instruction. That almost never works, even when the resulting fragment is a legal opcode. :)
The real instruction is:
3b 87 68 01 00 00 00 cmp 0x168(%edi),%eax
I'd guess you have some kind of hardware problem. It could also be a kernel problem where the saved address was corrupted during an interrupt, but that's not likely. -- MBTI: IXTP - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
