This doesn't appear to actually be fixed and the workaround of running
the below command no longer works on Ubuntu 13.04 with linux 3.8.0-18.
Is there a way to get the fix from 3.9 into 13.04? My system is so
unresponsive at times, and it happens fairly often, that I can't do
anything with the mouse.
