Bug#884061: 4.9.65-3+deb9u1 breaks things on AMD/Intel hybrid systems
Hi,
The last kernel security update (4.9.65-3+deb9u1) makes it impossible to
log in a gnome session from gdm3.
gdm3 starts correctly but when I try to start a gnome session, every
thing hangs and I have to hard reboot the machine (which makes it hard
to debug).
The system is an HP Zbook 15u G2 with hybrid AMD/Intel graphics.

Also, with kernel 4.9.65-3, I have some strange flickering on an
external display (display port).
I had to move to a backport kernel (4.13.0-0.bpo.1-amd64 #1 SMP Debian
4.13.13-1~bpo9+1) to get a usable machine.
