--- Comment #10 from dark_sylinc at yahoo.com.ar ---
I'm having the same problem; I'm using Ubuntu 18.04 LTS and whatever they
backported to kernel 5.4.0-51-generic started causing this problem; while the
problem goes away in 5.4.0-48-generic (Ubuntu flavors)

I have more information:

 - Card is Radeon RX 560 Series (POLARIS11, DRM 3.35.0, 5.4.0-48-generic, LLVM
10.0.1)
 - The bug sometimes also triggers when plugging or unplugging an HDMI TV.
(this may be https://bugzilla.kernel.org/show_bug.cgi?id=204241 ?)
 - The keyboard locks up, but I can still login via SSH
 - 'sudo shutdown now' will never finish. The kernel is stuck
 - In my case dmesg nor xorg.log notice at all something went wrong
 - Trying to kill X reveals the following:
