Public bug reported:
It seems that (almost daily) my system will "freeze" requiring a hard
power-off. I presume the problem is in the X server, as it simply stops
responding to keyboard / mouse inputs. It seems to happen when the
system is under heavy load.
I found these lines in the X log, which may be relevant to the issue:
