That was mine I think.  I never got a definitive explanation (it
happened only once and I didn't do a good enough job of information
gathering before re-booting - I plead early morning lack of focus) but
suspicion points at an unreliable USB DVB-T dongle.  It keeps locking up
and the Linux drivers do not cope well with an unresponsive dongle.
I've since taken it off the machine and there has been no recurrence.
