This sounds to me as though someone is trying to crack you from a
machine in Taiwan, but is probably throwing Intel shellcode at you,
which of course doesn't work.  And that this is collaborating with some
bug (software, hardware, I don't have enough information to even
speculate which) to lock up your machine.

It might be interesting to put a sniffer machine on its network
connection and capture a copy of the network traffic in question.
Identifying it may be hard, though.  Neither nor has a name, those being the two obvious addresses based
on the name in your logs; is in duPont space and
unlikely to be returning a name, whereas is
in APNIC space but seems to have no further info; as near as I can tell
the whole /8 is assigned to APNIC.  TWNIC is not returning any response
and may even be off the air.  Traceroute to dies as soon
as it hits routers that maintain a full routing table (instead of just
having a default route pointing upstream).
