Interesting, I noticed bug 1122030 today - not sure if it's related. Since you have it at a gdb, could you do:
x/i $pc at the point it fails (possibly the disassemble command may work) to see what the instruction is. Also can you post the output of cat /proc/cpuinfo on your machine to see what the CPU claims to support.
