Public bug reported:
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.
