dmesg | grep radeon with radeon.dpm=0

My system is unable to boot with an MSI R7 370 Armor 2X unless I put
radeon.dpm=0 (or nomodeset) to the boot parameter.

Also any change to the power profile results in an immediate lock up with blank
screen or, sometimes, black and white vertical stripes.

I think my issue is related with #77394 and #76490. Probably wrong frequency or
voltages given that the MSI R7 370 Gaming 4G (which is the better version with
higher frequency) works with DPM
(http://www.phoronix.com/scan.php?page=article&item=linux-411-gallium&num=1)

Tested with Linux 3.16, 4.0 and 4.1.
