I verified the -proposed kernel fixes the issue:
10:59:35 AM CPU%usr %nice%sys %iowait%irq %soft %steal
%guest %gnice %idle
10:59:37 AM all0.010.000.080.000.000.010.00
20.68
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
artful' to 'verification-done-artful'. If the problem still exists,
change the tag

I built a test kernel with commit 61bd0f66ff92. The test kernel can be
downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1755979
Can you test this kernel and see if it resolves this bug?
Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb
