            Bug ID: 92260
           Summary: ASUS [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
          Assignee: dri-devel@lists.freedesktop.org

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 },".
