dmesg

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/e78654799135a788a941bacad3452fbd7083e518 fixes the Issue if a simular Line is added "{ PCI_VENDOR_ID_ATI, 0x6811, 0x1043, 0x2015, 0, 120000 },".
