Hmmm, that's odd. I haven't seen any other reports on this (on full system hangs that is).

It would be very hard to figure out what is going wrong without any form of logging of
an oops or something. Is there any way you can find out if any oops information is present?

What does Alt-SysRq-l tell us, what are the CPU's doing when the system is hung?
