Just FYI, with kernel version 5.9 and 5.10, I have been unable to get WiFi on RPi4B 8GB working with 2.4GHz. 5GHz works fine without vc4.ko and fails with vc4.ko. 2.4GHz WiFi is usable with Raspbian kernel 64-bit 5.10, so I am assuming my hardware is OK. Since I do not use 2.4GHz WiFi because it gets interfered by my microwave oven, I have not spent much time on investigating the cause... Best regards, Ryutaroh
