High CPU from kworker/0:x-kacpi_notify

Ubuntu 20.04 LTS

Update: this problem is fixed after I did "apt dist-upgrade" on 9/21/2020
Update again: Acutally not fixed. It happened again after unplug/plug the usb-c hub.

I recently got a USB-C Hub (Targus ACA958USZ). When it's plugged in, the laptop gives high cpu from process
I've found a few USB-C hubs from various manufactures with the same problem. I think they are of the same chipset.
