Created attachment 117032 [details] 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. lspci -nnk | grep VGA: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Curacao PRO [Radeon R7 370 / R9 270/370 OEM] [1002:6811] (rev 81)
