Bisect log

I just bisected the regression that has been affecting my R9 290 for a long
time. I ended up at the same commit as Furkan:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7050c6ef5f0e9bc5e6bf9eb035320b70f731b919

I also observed the same radeon_pm_info debug output:

On good commits:
uvd    disabled
vce    disabled
power level avg    sclk: 100000 mclk: 126000

On bad commits:
uvd    disabled
vce    disabled
power level avg    sclk: 100000 mclk: 15000

Please let me know if you need any more information, or if you want me to test
something for you.
