Subject: Fwd: iwlwifi: rfkill locking up kernel 6.5.12, 6.6.2

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> Rfkilling the iwlwifi can lock up my machine, rfkill will not respond and other networking related things (e.g. ip a or ip r)
> I see this on 6.5.12 and 6.6.2 (fedora kernel). On 6.5.11 it does not lockup AFAICT, but also shows kernel oops.
> WiFi Hardware: AC 8265
> 
> Kernel oops for 6.5.11:

See Bugzilla for the full thread.

Anyway, I'm adding this regression to regzbot:

#regzbot introduced: v6.5..v6.6 https://bugzilla.kernel.org/show_bug.cgi?id=218206
#regzbot rfkill AC 8265 locks up machine

Thanks.
