RPI4B no radio after hostapd and wpad update

[rpmoomin]

did an opkg update && upgrade this morning and router failed to initialize radio0 and wifi interface.

router: rpi 4B
openwrt version: 21-02-1

the 2 pkgs are updated:
wpad-basic-wolfssl - 2020-06-08-5a8b3662-35 - 2020-06-08-5a8b3662-37
hostapd-common - 2020-06-08-5a8b3662-35 - 2020-06-08-5a8b3662-37

lines from the log:

daemon.notice netifd: radio0 (946): command failed: I/O error (-5)

daemon.warn hostapd: wlan0: Could not connect to kernel driver
daemon.err hostapd: Interface initialization failed

any hint pls?

further in the log: daemon.err hostapd: Failed to initialize QoS Map
googled for this error and found a workaround here:
https://www.mail-archive.com/openwrt-devel@lists.openwrt.org/msg60620.html

uci set wireless.@wifi-iface[0].iw_qos_map_set="none"

set qos to none worked but I think I will revert back the update and wait for new
brcmfmac driver if that's the real issue here

thoughts?

Upgrading packages (via the CLI opkg upgrade command or the LuCI Upgrade... button) can result in major problems. It is generally highly discouraged, unless you know what you are doing or if there is specific instruction to do so.

@trendy ty for the advice! I am going back to stable.
