dmesg

Starting from kernel 4.7 (I tried 4.7.4, 4.9.40, 4.11.12, 4.13.0-rc4,
4.14.0-rc6), the whole system freeze, at least 1 time per day (usually it
freeze during the night when the system is idle). Only 1 time I successfully
got the "GPU HANG" on dmesg.

The last known good kernel is 4.6.7.

The hang does not occur if I disable i915 kernel module.

Xorg version is 1.18.3.</pre>
