My system is unable to boot with an ASUS Radeon R7 370 STRIX Gaming with 2GB (STRIX-R7370-DC20C-2GD5-GAMING) 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.
Tested with Linux 4.1 and 4.2.
I my issue is related with #91294. The Commit https://github.com/torvalds/linux/commit/e78654799135a788a941bacad3452fbd708... fixes the Issue if a simular Line is added "{ PCI_VENDOR_ID_ATI, 0x6811, 0x1043, 0x2015, 0, 120000 },".
