Title:
Missing wireless network interface after kernel 5.3.0-43 installed
Status in linux package in Ubuntu:
Incomplete
Bug description:
I apologize if this is a repeat of the bug I filed a couple of days
ago, but I don't see on launchpad that it shows I filed a bug, so I am
filling another. Also didn't know what to file the bug under so I
chose network-manager. It appears to be a bug with kernel 5.3.0-43.
I updated to latest kernel: initrd.img-5.3.0-43-generic and find that my
network is in airplane mode. ifconfig shows there is no wireless interface
setup. When I go back to kernel 5.3.0-42 everything is working correctly. I am
using an HP laptop.
I can see the wireless network controller with lshw:
lshw -C network
