Sometimes I can still ssh to the machine, other times I cannot. When I can ssh to the machine, I can sometimes use this to bring back the machine to a working state:

$ systemctl isolate rescue.target

and then

$ systemctl isolate graphical.target

The only other option I have is to physically reset the machine.

$ cat /etc/redhat-release
