I'm running current Tumbleweed on my "new" Thinkpad T480 using iwlwifi.
I have both KOTD kernel-default-6.9-rc and Tumbleweed's kernel-vanilla-6.8.x
installed, the latter as a way to recover if KOTD breaks :-)
Since the first 6.9-rc releases, my WIFI does not work.

The dmesg regarding anything wifi (not only iwlwifi) does not differ from the
working 6.8.x kernels, no additional error or missing line or anything.
I have no idea how to debug this any further, I would not even know what to
report upstream ;-)
The Thinkpad T480 should still be in use in high numbers, so I wonder how I can
be the only one seeing this issue?
