After 5.19.0-15, intel wifi 6 no longer available

[Jeffrey Baker]

Since 5.19.0-16, which is also the kernel that broke booting on 11/12-gen Intel graphics, my Intel wifi is no longer working. This continues with the present release candidate kernel package -21. The wifi status reports simply that it is "unavailable" and no means to make it "available" is evident to me.

On all prior kernels and Jammy it worked fine.

Possibly this is a NM bug. I have no idea.

This change was made by a bot.

[Jeffrey Baker (jwbaker)]

The 'unavailability' of the wifi interface is apparently a path-dependent bug in network manager or a related component. I was not able to fix it in place, but a scratch reinstall of Kinetic fixed it. So it can't be the kernel.
