            Bug ID: 107955
           Summary: AMDGPU driver keeps reloading on hybrid graphics
                    system causing stuttering.
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/AMDgpu
          Assignee: xorg-driver-ati at lists.x.org

Hi,

My system at the time of writing is a Lenovo Y40-80 with a Intel i7-5500U and a
AMD Radeon R9 M275 2GB. The OS I have installed is Arch Linux installed.


Linux Y40-80 4.18.7-arch1-1-ARCH #1 SMP PREEMPT Sun Sep 9 11:27:58 UTC 2018
x86_64 GNU/Linux

Right now it seems AMDGPU is constantly restarting itself and this reloading is
causing stuttering. I keep seeing the following two lines constantly repeating
in my 'dmesg' log.

[drm] PCIE gen 2 link speeds already enabled
amdgpu 0000:05:00.0: PCIE GART of 1024M enabled (table at 0x000000F400000000).



My goal is to make use of the integrated Intel graphics for everything and use
the AMD graphics when needed with PRIME. This sort of works but I don't know
why I'm getting those messages repeated over and over with stuttering.
