I also have had random system freezes ever since I upgraded from 18.04
to 18.10, Linux 4.18.0-10-generic, solved by always booting into
4.15.0-36-generic. When the freezes happen, the screen simply stops, and
no input is accepted, not even the usual REISUB.

Bug description:
First thing I notice is that the mouse cursor freezes as I'm using it,
then I hit the CAPS LOCK key and the LED indicator doesn't respond.
Then I try the "REISUB" command, but it doesn't do anything either.
Only a hard reset works, pressing down the power button for a few
seconds.
How to reproduce?
I couldn't figure out a consistent method. It is still random to me.
Version: Ubuntu 4.18.0-10.11-generic 4.18.12
System information attached.
Also happens under Arch Linux and Fedora.
I've talked to another user on IRC who seems to be having the same freezes.
