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 52.210.243.221 nor
221.243.210.52 has a name, those being the two obvious addresses based
on the name in your logs; 52.210.243.221 is in duPont space and
unlikely to be returning a seed.net.tw name, whereas 221.243.210.52 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 221.243.210.52 dies as soon
as it hits routers that maintain a full routing table (instead of just
having a default route pointing upstream).
