I merged some patches from Florian yesterday, but it could also be a problem with the defconfig changes
The bisection pointed to b02ec7658c98 ("ARM: multi_v7_defconfig: Enable some drivers for LS1021A")
I've rebased my tree with arm-soc for-next, and reverted the commits listed above. Should know shortly if the reverts fix the boot issues.
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?
