Comment 33 for bug 1386534

There are a few commits specific to radeon in 3.13.11.7:

aed6386 drm/radeon: tweak ACCEL_WORKING2 query for hawaii
519eac7 drm/radeon: use packet2 for nop on hawaii with old firmware
c031389 drm/radeon: re-enable dpm by default on BTC
43ee795 drm/radeon: re-enable dpm by default on cayman
1e22169 drm/radeon/dpm: handle voltage info fetching on hawaii
6f846eb drm/radeon/atom: add new voltage fetch function for hawaii
382d6be drm/radeon: set VM base addr using the PFP v2
7b421b8 drm/radeon: load the lm63 driver for an lm64 thermal chip.

Before starting a bisect, I'll build some test kernel with a few of these commits removed to see if we can narrow down if any of these commits caused the bug.

I built a test kernel up to the following commit: 1e22169

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1386534

Can you test this kernel and see if it has the bug or not?
