I have been getting this weird error when I put my laptop to sleep and then waking it up after a while. This error forces me to force reboot my computer in order to restart my computer. However wifi and ethernet works fine so I am not sure why this error appears. It usually appears when I put my laptop to sleep and then leave the network then reopening it in my home using my home network.

When I last checked this error is from iwlwifi. Below is the return from the command dmesg | grep iwlwifi

My wifi card is Intel Ac 9560

00:14.3 Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)

Bug 205513 - iwlwifi: Change log level of "iwlwifi 0000:6f:00.0: BIOS contains WGDS but no WRDS" to "info" has been fixed in Linux kernel.

From the ticket:

We have investigated the issue and it turns out that the reference
implementation of the BIOS recommends having WGDS set to NOP values
when WRDS is not included. This is what is causing the problem in so
many platforms. The error message itself is harmless, so I'm going to
reduce the logging level as suggested.
