I do see them sometimes at boot, about the time plymouth is about to kick in but most of the time I can reproduce the issue by giving the GPU some work. For example, I can trigger the issue by running: vblank_mode=0 glxgears After 10 to 15 seconds, the screen would then freeze. Then go blank as it was trying to reset itself then display the screen again before starting another reset loop. The system is then not responsive unless via SSH, which I then use to restart the display-manager service. Upon restarting it, the screen either is full of white noise (can't see anything but noise in it) or it has a frozen image of what it was there when the lockup happened. The mouse pointer is still visible and responding. Looking at other bugs, this could be related to https://bugs.freedesktop.org/show_bug.cgi?id=67722 though the GPU is different. I'm booting with radeon.dpm=1. Booting without that option renders the screen unusable (https://bugzilla.kernel.org/show_bug.cgi?id=82431).
More Details which might be relevant and might have missed the first time around: Other packages: linux-firmware 20170422.ade8332-1 kernel 4.11.9-1 Xorg driver: xf86-video-ati 1:7.9.0-1 Have also seen the following when booting the radeon kernel module is loaded: Jul 21 09:51:06 hostname kernel: [drm:uvd_v1_0_start [radeon]] *ERROR* UVD not responding, giving up!!! Jul 21 09:51:06 hostname kernel: radeon 0000:01:00.0: failed initializing UVD (-1). Jul 21 09:51:06 hostname kernel: [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait timed out. Jul 21 09:51:06 hostname kernel: [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed testing IB on GFX ring (-110). Jul 21 09:51:06 hostname kernel: [drm:radeon_device_init [radeon]] *ERROR* ib ring test failed (-110). Current situation: GDM with Wayland shows only white noise on the screen. Switching to Xorg shows the desktop as expected however it seems it is not using the radeon driver. As glxinfo puts it: OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 4.0, 256 bits)
I don't have this laptop anymore. It might have been a motherboard issue as the laptop stopped booting not long after this issue.
