            Bug ID: 103271
           Summary: AMD R9 270X Flickering with DPM Enabled on Linux 4.1
                    with RadeonSI
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.1.6
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: wittyman37 at yahoo.com
        Regression: No

I upgraded my system today from the 4.0 kernel to 4.1. After rebooting, I am
getting crazy flickering that makes my system unusable. I rebooted and disabled
dynamic power management with radeon.dpm=0 as a kernel parameter. The
flickering is now gone. I have an R9270X running with the open source drivers.
I did a quick search and could not find a similar issue anywhere. Does anyone
have any suggestions?

UPDATE: I built the kernel using the linux-git package in AUR and have the same
issue with DPM. linux-git 4.2rc7
