When booting 4.9.3 kernel , gdm starts with a black/gray screen. Some bisecting
gave the results below.
I found that 4.9.3 kernel (from linux-stable) after reverting commit
0ce140d45a8398b501934ac289aef0eb7f47c596, the problem is fixed. Relevant output
from the logs (4.9.3-1-g17a6527 is the one with the reverted patch):
Command line: BOOT_IMAGE=/vmlinuz-4.9.3-1-g17a6527+ root=/dev/mapper/vg0-root
ro rd.auto=1
Command line: BOOT_IMAGE=/vmlinuz-4.9.3 root=/dev/mapper/vg0-root ro rd.auto=1
