Title:
  system is wedged, new ssh connections are closed instantly and console
  is black with a mouse but does not accept keyboard input

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  This started happening on Thursday November 4th.

  This only seems to happen when the host is idle at the console.
  although a KVM instance was actively being used on one of the effected
  hosts.

  The system will hang and will be unresponsive to any keyboard input
  although you can see a mouse cursor.

  ssh connections are closed as if they were filtered.

  ctl-alt F* does not work

  oddly enough a windows KVM host was still responsive.

  A coworker is also having this issue with his machine which is running
  vm's in virtualbox

  Both systems are Dell Optiplex 960s

  The system did not respond to a soft shutdown with the power button

  We were forced to reboot by using the NMI shutdown by holding the
  power button down.

  Unfortunately it appears that syslog just quit logging and there are
  no errors in any log files.

  We both did run updates and here is the entry of what was updated that
  day on my machine.
