Title:
Internet disconnected unexpectly + Xorg freeze while watching html5
video in Chrome

Status in linux package in Ubuntu:
In Progress

Bug description:
A few issues:

1)With Intel(R) Wireless-AC 9560, under kernel 5.4 for Ubuntu 20.04.1,
the system sometimes gets disconnected with the network and I get the
following error in syslog:

iwlwifi: BIOS contains WGDS but no WRDS

It is unclear if this is the cause of the problem, but this is likely
related to kernel.

2) Watching HTML5 videos on Chrome with Nvidia GPU (440 driver) will
sometimes cause xorg freeze. The exact cause is unknown. (Mouse,
control all freeze for 5-10 seconds)

3) After Wake up from sleep got the following error on screen

sof-audio-pci error: no reply expected, received 0x0
iwlwifi: BIOS contains WGDS but no WRDS

4) After wake up from a long sleep session, sometimes chrome will not
render web page correctly or even freeze. It is unclear if its a
Chrome problem, or a Nvidia problem, or a Kernel Problem.
