>From time to time (once every 2 hours), during the work (key press??), display
blacks for ~2seconds. After that, everything restores an is fine again.

Once that happens, dmesg says:
*ERROR* CPU pipe B FIFO underrun

Dmesg with debug output is attached.

I tried to run intel-drm kernel but I was consistently getting "double free"
