I'm using a ThinkPad X1 Carbon Gen 6 and I faced the same problem. I then found out that it only happened after waking up from hibernation. Are you using hibernation too? If yes, try removing the xmm7360 module before hibernation. This is how I do it on my Arch Linux by writing an automated hibernate script:

1. Run this to create the file

sudo nvim /lib/systemd/system-sleep/xmm63.sh

2. Paste the following code

#!bin/sh

case $1 in
	pre)
		rmmod xmm7360
		;;
	post)
		modprobe xmm7360
		;;
esac

3. Save and run this

sudo chmod +x /lib/systemd/system-sleep/xmm63.sh
