Indeed. I tried using modeset X11 driver and got a bunch of errors in
Xorg.0.log about inability to do "page flips", so I've put `PageFlip false` for
it and `EnablePageFlip false` for amdgpu with removal of 'TearFree true' (why
it isn't always on by default ?), just in case. No hangs for about 24 hours
even with a lot of Youtube in Firefox even with amdgpu.

There seem to be a lot of patches for AMD GPUs queued for 5.2.5, any chance of
the complete fix among them ?
