Fedora 30 5.2.11-200.fc30.x86-64 was working smoothly.
An update download and install was suggested and I accepted.
And went to do some other things leaving the computer alone.
Apparently, version 5.3.6-200.fc30.x86_64 was installed.
When I came back I found a screen halted with the screen full of this log.
You should see more details if you remove ‘quiet’ from the kernel command line. On the grub menu you see when you boot, press E to edit the entry, locate the ‘linux’ line and remove the word ‘quiet’ from it. Press Ctrl-X to go ahead and boot. The change is not permanent, it’ll be noisy, but it’ll help you see more details.
Your issue look similiar to the issue of this user what was solved ( It is in case you have a Nvidia card and did install the privative driver in the same way that the user commented).

This goes in the same place where you wrote enforcing=0 on the linux line. You should find yourself in single user mode where it’ll ask for the root password. Enter that and you should be able to look through journalctl for clues on what’s keeping the machine from fully booting. Incidentally, you don’t have nvidia drivers or other custom shenanigans going on right?
