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.
