Suspend in kernel 5.11 causes the whole network to go down

[Jonas Gamao]

I am currently reporting on kernel 5.8 (HWE) on KDE Neon Testing Edition (Ubuntu 20.04). I was mainly on 5.11, tried both kernels from Ubuntu and Pop!_OS.

Every time I put the PC on sleep, the whole network will go down after waking up. Only fix I managed is to fully reboot it.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1938647

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Please note: `ubuntu-bug`, `apport` & bug reporting tools are provided with Ubuntu by default, many require manual addition for some releases of downstream OSes based on Ubuntu (eg. Linux Mint). You should check with your distribution first.

'focal' is a release name and not the name of a
package currently in a supported release of Ubuntu.
