Comment 40 for bug 1210858

Hi,

so, what did work is to use the patch supplied here on a self-compiled linux-3.11.

The patch from: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1210858/comments/32
The Sources build from the guide: https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
With the checkout: git clone git://kernel.ubuntu.com/ubuntu/ubuntu-saucy.git

And built with:
fakeroot debian/rules clean
fakeroot debian/rules binary-headers binary-generic

What DID NOT work was to install linux-3.12-rc7 from mainline ppa: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-rc7-saucy/
My understanding was that linux 3.12 includes the patch for this problem.
This is obviously not the case.
