Bug Description
Asus Zenbook Flip S (UX-370UAR). Intel Core i7-8550U CPU).
The X freezes and doesnt even allow to start a console session.
Only happening on Ubuntu 18.04 and 20.04.
Does not happen in the same computer under Ubuntu 16.04 or Windows 10.
Can be replicated easily. Every time I plug/unplug the power USB-C or the USB-c hub. Mostly, on any interaction with the USB-c or I/O ports.
If I plug/unplug the USB-c without X in a console session (CTRL+ALT+F3) I get the following:
BUG: kernel NULL point dereference, address: 0000000000000080
