Bug#985632: firmware-brcm80211: [REGRESSION] RPi4B 5GHz WiFi stopped working with 20210208-4, 20201218-3 was fine



Package: firmware-brcm80211
Version: 20210208-4
Severity: grave
Tags: sid bullseye
Justification: renders package unusable
X-Debbugs-Cc: debian-arm@lists.debian.org

Dear Maintainer,

5GHz WiFi stopped working with 20210208-4.
iw wlan0 scan does not show SSID of 5GHz WiFi.
With 20201218-3, 5GHz worked fine,
provided that vc4.ko is blacklisted (see #981616).

I will see if the newer package in the experimental
behaves differently.
