Intel bug file

We using ubuntu on desktop. Some desktops are tool old. There is two machines
with identical configuration. After installing on it new version of ubuntu
(16.04->18.04) users cannot work as early. XServer crashes while increasing the
load on the processor (we think so).

Our typical case is using Intel for run Xserver. Nvidia for GPU calculations.
We tried upgrade a kernel to latest stable mainline (4.17.4-041704-generic) but
unfortunately this does not help.

Running X on nvidia is stable, but gpu memory is used.
