Raspberry Pi 3B+ WiFi - Unable to set region, possible udev issue

Raspberry Pi 3B+ on board wifi fails to start.

alpinepi:/# iwlist wlan0 scan
wlan0 Interface doesn’t support scanning : Interrupted system call

alpinepi:/# rfkill list
0: phy0: wlan
Soft blocked: no
Hard blocked: no

Some misc internet posts suggest that you have to set the regulatory domain before the interface will come up. Tried to set many ways including wpa_supplicant, iw, and setting a modprobe.d config.
alpinepi:/# cat /etc/modprobe.d/cfg80211.conf
options cfg80211 ieee80211_regdom=US

At this point i believe its either firmware or possibly a udev issue.

in modloop that might match. ref #9549
