Public bug reported:
About 75% of the time for the past few weeks (I don't have a time where
this started), my wifi is not working after resume from suspend. I'm
happy to provide more debugging info if needed.
I have tried an rmmod/modprobe on on the iwlwifi,iwlmvm modules just to
see after the resume, and didn't re-enable the card.
The symptoms are, the wlp4so interface is DOWN, I can't bring it up.
gnome-network-manager widget turning the interface off/on doesn't work.
I don't see anything glaring in dmesg.
