Latest kernel kills wifi.

[Patrick M]

New kernel 6.0.5-14 boot up system does not recognize built in wifi adapter. When I drop to last kernel install wifi works fine.

HP Pavillion With intel core I7 chip.

Thank you for the reply. I had to apply the command twice. It gave me an
error the first time. Report was sent ( I think)

Has anyone figured out a patch for this? there was an update today, which I applied. Did not change anything with new kernel, but now old version boots to airplane mode. I can get the wifi going on older kernel still.

Any news on this bug? Latest patches did not affect it

I think Connman is the culprit?
