I've looked at the built-in drivers to see if they might do something
on unrelated hardware (we've had bugs like that before), but didn't
find anything: the watchdog and cpufreq drivers all look sane, everything
else is a loadable module.

One possible explanation would be a buggy bootloader that fails to pass
a correct initrd and/or dtb if the kernel image gets too big.

Do you know if there is an initrd that is passed on this platform?
