Bug#981586: Bullseye armhf kernel for Raspberry Pi 4b does not boot
Analysis showed that it does reach init-top. But when usbcore and usbhid
are loaded, peripherals like mouse and keyboard are not at all detected.
When later usbhid, usb_storage and uas should be started, they do not
work either and the root file device is not detected.
What you wrote implies that / resides on an USB device.
Sounds very much like a duplicate of #977694
Can you verify if the workaround of manually adding the
reset_raspberrypi module to initramfs works?

Alternatively, install initramfs-tools 0.140, which is currently
available in sid, and rebuild your initramfs.
The same problem exists also for Buster armhf.
What kernel version did you use on Buster armhf that was also affected?
If it's a 5.10 kernel from buster-backports, it should also be affected
by #977684
However, Bullseye 64 Bit (...) does work as expected.
What kernel version did you use on Bullseye arm64 that was *not* affected?
If it's a 5.9 kernel from a tested image, it shouldn't be affected.
Building 5.9 against the Ubuntu 5.4 kernel config also does work.
5.9 would not be affected. This is specific to 5.10, which added the
reset_raspberrypi module.
If all of the above checks out, this is most likely a duplicate of #977694
Best regards,
