If you downgrade wireless-regdb to 2019.06.03-1 can you reproduce the issue?

I'll check it. At the moment, I think about it, to remove the whole crda and regulatory stuff from
my (penetration testing) systems, because this issue causes several other issues:
https://bugzilla.kernel.org/show_bug.cgi?id=208483
https://github.com/openwrt/mt76/issues/425

Downgrading lead to more issues:
cfg80211: failed to load regulatory.db
8821ce: Unknown symbol __cfg80211_alloc_event_skb (err -2)
8821ce: Unknown symbol cfg80211_remain_on_channel_expired (err -2)
...

and we have to downgrade much more packages.

Unfortunately the issue prevent to inject packets on 5GHz.

Looks like the issue exist since last year (on other distros, too):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=810384

wireless-regdom is set according to https://wiki.archlinux.org/index.php/Network_configuration/Wireless
$ cat /etc/conf.d/wireless-regdom | grep -v "#"
WIRELESS_REGDOM="DE"

and country is definitely not set:
$ dmesg | grep cfg
[ 5.926802] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[ 5.930678] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'

that makes the whole system restricted as hell.

We should also take a closer look at libnl. It could be possible that libnl caused the issue.
