Bug ID: 91294
Summary: [R7 370] DPM and power profile change crash the system
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Radeon

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

Tested with Linux 3.16, 4.0 and 4.1.
