Description of problem: Complete system freeze requiring hard pawer off/on cycle and reboot. This is on latest Fedora 27 distribution running on Ryzen 2500U with latest amdgpu from Fedora 27 distribution. (Nothing custome here) Version-Release number of selected component (if applicable): Firefox Version 59.0.1 (64-bit). Also happens with Thunderbird 52.6.0 How reproducible: Just regular browsing. No clear pattern yet. Sometimes while entering data in for example Bugzilla or new email compose. Does not seem related to video playback such as in Youtube. If I turn off hardware acceleration the problem goes away. I suspect related to amdgpu, but dont know where else to start.

I had another freeze outside of firefox and thunderbird so moving this to amdpro. I have removed one gnome extension to see if it is the culprit. Regardless, the system should never freeze.
Moving this to 1562530. The fact that I can't get a kernel panic showing I think is a tell tale on this *** This bug has been marked as a duplicate of bug 1562530 ***
