Comment 20 for bug 1133835

David Tombs, could you please execute the following at a terminal, boot into the kernel, and advise to the results (the expectation is that this will not produce the problem):
cd ~/Desktop && git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-stable && cd linux-stable && git checkout 6015ff103133c7e50a753c198c69bcabc3a5e3b0 && cp /boot/config-`uname -r` .config && yes '' | make oldconfig && make-kpkg clean && CONCURRENCY_LEVEL=`getconf _NPROCESSORS_ONLN` fakeroot make-kpkg --initrd --append-to-version=-custom2 kernel_image kernel_headers && cd .. && sudo dpkg -i *.deb
