Thanks for testing. That means a fix for this bug is in the mainline
kernel. I'll check with upstream and see if the fix for this was cc'd
to stable.

I updated upstream with your testing results.
Could you also give the latest mainline kernel a test, to see if it also
exhibits this bug? It can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc7-trusty/

3.13.0-031300rc7-generic_3.13.0-031300rc7.201401041835 works fine, I
don't experienced crashes
However I can't use it as is since it lacks a proper NVidia driver link
and I can't use my dual-screen, plus I must start manually my
WindowManager since it doesn't start correctly after X loads.
But
We received a patch from upstream.
I built a Saucy test kernel with the patch applied.
The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1249880
Can you test that kernel and report back if it has the bug or not?
Thanks again for all the help testing!

You
3.11.0-15-generic_3.11.0-15.22~lp1249880Patched doesn't work well.
the moment I start my VM the system become unresponsible. A bit
different than with 3.11.0-13 tough, the mouse still moves around, but
you can't do anything, the whole desktop is in a frozen state.
on a side note just released
Thanks for testing! I'll send a message upstream to the patch author
and request some feedback.

And the bug does not exist with v3.11.4? If that is the case, I will
start a kernel bisect between v3.11.4 and v3.11.5. The bisect will
require testing of about 7 - 10 kernels, but it will identify the commit
