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: ``` [ 0.000000] Linux version 4.10.0-22-generic (buildd@lcy01-08) (gcc version 6.3.0 20170406 (Ubuntu 6.3.0-12ubuntu2) ) #24-Ubuntu SMP Mon May 22 17:43:20 UTC 2017 (Ubuntu 4.10.0-22.24-generic 4.10.15) [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.10.0-22-generic root=UUID=5f1b119b-2beb-4d5b-aabf-606390f6d767 ro [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] Centaur CentaurHauls [ 0.000000] x86/fpu: Supporting XSAVE feature 0x001: 'x87 floating point registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x002: 'SSE registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x004: 'AVX registers' [ 0.000000] x86/fpu: xstate_offset[2]: 576, xstate_sizes[2]: 256 [ 0.000000] x86/fpu: Enabled xstate features 0x7, context size is 832 bytes, using 'standard' format.
