it happens not only after reboot, but also when restarting lightdm.
When frozen even REISUB magic commands have no effect (so i suggest this bug is
of great importance).
The only trace of crash in logs is few lines of NUL (written as ^@ )
spec:
Clevo N850 HK1
Kubuntu 17.04 with 4.10.0-21-generic
** Changed in: lightdm
