Control: reassign 981616 firmware-brcm80211 20201218-3 Hi, two RPi4B 5GHz WiFi problems #985632 firmware-brcm80211: [REGRESSION] RPi4B 5GHz WiFi stopped working with 20210208-4, 20201218-3 was fine and #981616 5GHz WiFi does not work with vc4.ko on RPi4 and 4K display completely went away by replacing /lib/firmware/brcm/brcmfmac43455-sdio.bin and /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob by the files at https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm Commit messages at https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm are interesting: Use BCM43456 clm_blob on CYW43455 The previous CYW43455 clm_blob provides limited access to the higher 5GHz channels (100+) - the BCM43456 (surprisingly) seems to work and doesn't have this problem. Huh???? Update CYW43455 firmware This release fixes the error: Firmware trap: type 0x4 @ epc 0x0007a094 The full version string is: Version 7.45.229 (617f1f5 CY) CRC: 253bd863 Date: Mon 2021-01-04 19:58:58 PST Ucode Ver: 1043.2160 FWID 01-2dbd9d2e See: raspberrypi/linux#3849 Best regards, Ryutaroh Matsumoto

Could you update both bug with updated firmware?
