kernel 4.17.3

[166313.855821] drm: not enough stolen space for compressed buffer (need
50688000 more bytes), disabling. Hint: you may be able to increase stolen
memory size in the BIOS to avoid this.
[166320.700776] [drm] GPU HANG: ecode 9:-1:0x00000000, reason: Kicking stuck
wait on rcs0, action: reset
[166320.700778] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[166320.700778] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[166320.700779] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[166320.700780] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

[166327.715066] [drm] Reducing the compressed framebuffer size. This may lead
to less power savings than a non-reduced-size. Try to increase stolen memory
size if available in BIOS.
