Describe the bug

I used prebuilt images on rpi 4b, version shows 6.1.21, 32bit, all features are passing. Checked out the kernel version 6.1.45, built 32 bit and flashed the images as per rpi documentation, wifi, Bluetooth, audio and hdmi audio, fails to work, it looks drivers are not loading. Kindly help and guide further.

Can you report output of uname -a?

Note: that pi4 defaults to a 64-bit kernel (even on 32-bit image) on recent versions of RPiOS.

No, the whole line.

I shifted to 6.5 kernel, the issue is visible on 6.5 kernel as well. dmesg attached as well. msl@raspberrypi:~$ uname -ar Linux raspberrypi 6.5.0-rc6-v7l+ #6 SMP Sat Sep 30 18:54:21 IST 2023 armv7l GNU/Linux dmesg-6.5-sb.txt
