I'm having an issue on a Kaby Lake based device, where toggling CAPS LOCK on works, but toggling it off crashes the machine. The screen becomes glitched looking, and sometimes static plays over the speakers. Changing Desktop Environments and Window Managers does not change this. Dropping to a terminal via ctrl+alt+F1 seems to be unaffected. I thought this was an issue with X11 as per this (https://wiki.ubuntu.com/X/Troubleshooting/Freeze), but if I ssh into the machine, it becomes unresponsive after the crash.
