Title:
Dell XPS 9300 stops responding

Status in linux package in Ubuntu:
Confirmed

Bug description:
I installed Ubuntu 20.04 on a new Dell XPS 13 9300 a few weeks ago and
have been experiencing a number of hangs, where keyboard and mouse
stop responding, requiring a reboot.

I have two LG 27" monitors connected, one of which acts as a usb hub
for an external apple keyboard and trackpad.

I've attached a journal from the last boot that crashed using

journalctl -b -1 --no-hostname -k > dmesg.txt

Any help would be appreciated.

Regards,

Kim
