Reproducible? This is probably a regression in wext handling. Please try with iw. (In reply to Emmanuel Grumbach from comment #2) > Reproducible?

Removing Intel from here. Ah sorry. I got confused by your Realtek device asking for FW. Sorry... Please try with iw (note that I already asked that in July... Hi Emmanuel, thank for hints. I installed net-wireless/iw-4.3 from Gentoo tree (https://git.kernel.org/cgit/linux/kernel/git/jberg/iw.git/), what command do you want me to try? The above messages happen during network being started by OpenRC I guess so do I have to disable the wireless networking in /etc/conf.d/net before fiddling with "iw" utility? Then I'd warmly recommend that OpenRC moves to use nl80211 APIs and not the old WEXT interface. This doesn't allow the kernel to introduce regressions of course. In this case, I don't really see what OpenRC tries to do but it seems quite insane. It tries to change the Tx power of a device that doesn't exist yet or something like that. Do you have a way to record tracing? Can you try with this patch on OpenRC?
