Comment 5 for bug 1813543

Ubuntu 18.04.1 LTS
Linux XXX 4.15.0-43-generic #46-Ubuntu SMP Thu Dec 6 14:45:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I can't log in to a wayland or xorg session at gdm3 screen with kernel 4.15.0-44
Just a black screen. I can't even switch to another tty. Full system hang.

Maybe this is related. Seems to be a kernel driver module problem.

I am on a Thinkpad T460p with intel/nvidia graphics stack using nouveau.

VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
3D controller: NVIDIA Corporation GM108M [GeForce 940MX] (rev a2)

Booting the previous 4.15.0-43 is just fine.
