Hello,

I'm running a Thinkpad T480, lspci reports
03:00.0 0280: 8086:24fd (rev 78)
Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)
Subsystem: Intel Corporation Dual Band Wireless-AC 8265 [Windstorm Peak]

Using 6.8 kernels, everything is fine (the first kernel I ever used on
this machine was 6.8.1 from openSUSE Tumbleweed).

Since 6.9-rc1 (using precompiled SUSE Kernel-of-the-day), wireless just
does not work.

Nothing suspicious in dmesg, NetworkManager does nothing and a manual

mixi:~ # ip link set up dev wlp3s0
RTNETLINK answers: Invalid argument

I think you may need this fix:

Yes, this fixes it (applied manually, just built iwlmvm, rebooted into 6.9-rc4 and loaded the patched module => wifi is happy :-)

Thanks, saved my weekend :-)
