Comment 23 for bug 1680904

Same issue with generic variant from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2017-06-01/ this morning.

Also tried to select recovery mode in grub, no better: I only get a black console screen with a blinking cursor in the upper left.

No error message, nothing in the logs.

FWIW, here's the very beginning of dmesg with zesty's standard kernel:
