https://bugs.freedesktop.org/show_bug.cgi?id=100423

--- Comment #3 from Johnny B. Goode <adamos at hell.factory.net.pl> ---
Almost same for i7-6700, GM206 [GTX 950]
No touch screen, no hybrid graphics. Pure desktop. Intel 530 on chip but
disabled in BIOS. Only one Asus Graphic Card.
Problem started on Kernel 4.10.x and is going on 4.11.0. Kernel 4.9.x is FAULT
free. Different distributions Fedora 25, Gentoo.

Should I open a new bug with "FAULT at 10eb14" or is it this same issue?
