Hi

sometimes when I issue the reboot command it'll get stuck at a graphical boot screen. I don't know if it is during shutting down, or booting up. I then hardware-reset it and it'll boot successfully.

How can I troubleshoot this?

I'm running openSUSE Leap 42.3 in a Hyper-V virtual machine. The installation started as openSUSE 13.2 or so and it didn't have this problem. Now, after several distribution upgrades this is occurring.
