Title:
  1002:94c3 (EE) [mi] EQ overflowing. Additional events will be
  discarded until existing events are processed

Status in “xorg” package in Ubuntu:
  Expired

Bug description:
  Random screen freezes (see also https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1184451).
  Sometimes system is hanging and it looks like swapping is active (but swap is disabled completely), no response to either mouse/keyboard. Switching to terminals (Ctrl+Alt+F1-F6) and Alt+SysRq is still working. In Xorh.0.log there are next messages:

  [258008.925] [mi] EQ overflowing.  Additional events will be discarded until existing events are processed.
  [258009.690] [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
  [258009.690] [mi] mieq is *NOT* the cause.  It is a victim.
  [258009.690] [mi] Increasing EQ size to 512 to prevent dropped events.
  [258009.691] [mi] EQ processing has resumed after 67 dropped events.
  [258009.691] [mi] This may be caused my a misbehaving driver monopolizing the server's resources.

  I use radeon driver.
