            Bug ID: 107149
           Summary: Resuming from suspend can cause not working hw
                    acceleration
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: kami911@gmail.com

Sometimes when my machine come back from suspend the hw acceleration is stopped
to work. Kernel messages:
https://bugzilla.mozilla.org/attachment.cgi?id=8989152

I updated my system to Ubuntu 18.04 based Linux Mint 19 recently so I have this
X:
X.Org X Server 1.19.6

I used radeon driver that time, but now I switched to AMDGPU driver and 4.17
kernel. This laptop has two video cards, one integrated from Intel and another
from AMD.

As you can see from the kernel parameters I was manage to use amdgpu driver
with the build in AMD GPU. Time by time something happen (maybe related to ACPI
events) and Firefox is stop working. I have to restart Firefox, but I got this
error in terminal:

Also glxinfo has problem:
