83 ca 10 or $0x10,%edx
3b .byte 0x3b
87 68 01 xchg %ebp,0x1(%eax) <=====
00 00 add %al,(%eax)
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.
