OK, this line in your oops: Unable to handle kernel paging request at virtual address 5a5a5a5a Probably means we hit some slab poison with DEBUG_SLAB set. Looks like your config boots fine with DEBUG_SLAB disabled for me. As this only happens for timer12, I wonder if we're again hitting some uncompress issue with corrupted dtb. Changing u-boot ftdaddr higher up might possibly make it go away. Or else there's a bug elsewhere :) Regards, Tony
