In fact, you do have a buggy chip. There's some eight-byte
instruction sequence (beginning with the two bytes F0 0F) that, if
allowed to complete, will cause the system to lock up hard. The Linux
kernel has had a patch to fix this for a long time, though; you
shouldn't worry about it.
You might try 'cat /proc/cpuinfo' to see what else Linux has to say
about your CPU; if it's sufficiently old, it might have the famed FDIV
bug, too. :-)
