--- Comment #46 from Rob <rob at canthelpyou.com> ---
I'm getting the same error with a GM965/GL960 controller, too.

On kernel 4.8.0-2-amd64 and 4.9.0-1-amd64 this results in a kernel freeze
during the boot process. Found a "vblank wait timed out on crtc 0" with a
following "Call Trace" in an old kern.log with a 4.7.0-1-amd64, too but during
that time that doesn't result in a kernel freeze.

Hardware:
Acer Extensa 5220

Architecture:
X86_64

Kernel:
4.7.0-1-amd64
4.8.0-2-amd64
4.9.0-1-amd64

Distribution:
Debian testing/sid

Workaround to skip the freeze during the boot process:
Boot kernel in recovery mode and skip root login with Ctrl+D
