With Linux 4.17.0rc2 - Linux 4.17.1 boot process always stuck for three-five minutes at the stage when gdm3 is ready to start Xorg (cursor appear on the screen, Plymouth splash disappear, Gnome Shell desktop loads).

With Linux drm-tip (cod/tip/drm-tip/2018-06-16, 02d8db1a894b0e646b2debd64ce24b8e99fd2ffd) couple of times system started normally, but after that I getting same behaviour as with Linux 4.17.0rc2 - Linux 4.17.1. 

Startup finished in 7.524s (firmware) + 8.012s (loader) + 7.960s (kernel) + 4min 11.905s (userspace) = 4min 35.403s
graphical.target reached after 4min 9.959s in userspace

systemd-analyze blame:
     4min 4.390s plymouth-quit-wait.service
          2.406s NetworkManager-wait-online.service
          1.510s plymouth-start.service
