(EE) [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
(EE) [mi] mieq is *NOT* the cause. It is a victim.
(EE) [mi] EQ overflow continuing. 100 events have been dropped.

[ 2596.886] [mi] Increasing EQ size to 512 to prevent dropped events.
[ 2596.887] [mi] EQ processing has resumed after 121 dropped events.
[ 2596.887] [mi] This may be caused my a misbehaving driver monopolizing the server's resources.
This is mostly a "oh dear, this was slower than I thought" backtrace. There's a patch to mitigate this in Fedora 18 by bumping the default queue size; we should apply it for 6.4 too. Devel ack.
