Comment 35 for bug 1543683

I built a Xenial test kernel with the following commit requested by upstream:

    drm/i915: Fix hpd live status bits for g4x

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1543683/patched-kernel/

Can you give this test kernel a try and see if it resolves the bug?

Note, with this test kernel, you need to install both the linux-image and linux-image-extra .deb packages.
