linux-raspberrypi to 5.10.73-1 no longer boots on Raspberry Pi2 ARMv7

[renkei]

On Arch Linux ARM on my Pi2, after an update from 5.10.64-1 to 5.10.73-1 (see core/linux-raspberrypi to 5.10.73-1) the Linux kernel cannot boot anymore.

I've uploded a screenshot of the "Unable to handle NULL pointer dereference at virtual address 00000000" message here Raspberry Pi 2B+ no longer boots after latest kernel update

Some forum users have also reported the breakage on RPi 1 and RPi Zero. Link to thread. I do not see this on RPi4 but that uses a slightly different kernel package/config due to changes in bootloaders for a few years ago.

Sorry guys - there was an upstream back-port introduced into 5.10.65 that required more downstream fixups for older platforms than were actually applied (the sdhost driver isn't normally used on Pi 4). Mea culpa.

The remaining patches are in rpi-5.10.y now, and we'll push out an rpi-update build later on.

@pelwell - Several users of RPi2 have confirmed that the updates in rpi-5.10.y fix the boot issue. Thanks for the quick engagement. You can close this ticket from my perspective.

The fix should now be in rpi-update kernel.

Thanks for the quick help. After the update to 5.10.73-2 it works again. Great!
