Kernel messages as reported by journalctl -b -1.

On a Dell Latitute E6410 laptop with the following display adapter:

01:00.0 VGA compatible controller: NVIDIA Corporation GT218M [NVS 3100M] (rev
a2)

Some time ago (kernel 4.10.0) the kernel drm module stopped working, the
display is all messed up after boot and stays so. The first line on the screen
says "Starting version 234" which refers to Systemd version 234. The rest of
the screen in unintelligible.

I'm running Arch Linux. The problem is still there with the latest kernel.

I did a git bisect on the kernel and found the following:

first bad commit: [df8dc97cd17269474344d73cc02739532c468d04]
drm/nouveau/kms/nv50: use drm core i2c-over-aux algorithm
