        <pre>Artem, you have two different issues here. Regarding watermark (with the
backtrace from kernel log that you have pasted), I recommend to update your
kernel because there were recently some improvement done (see
<a href="https://cgit.freedesktop.org/drm-intel/log/drivers/gpu/drm/i915/intel_pm.c">https://cgit.freedesktop.org/drm-intel/log/drivers/gpu/drm/i915/intel_pm.c</a>)

Regarding the second one, GPU Hang, assigning to Mesa product.
