Public bug reported:
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.
