The first screenshot did show some problem, mostly likely in grub.cfg, but did
not cease booting. As far as I know, some kiwi config seems to set $prefix
wrongly at very beginning hence grub couldn't look up its modules, and shortly
after the $prefix gets corrected everything start to work as expected.

The real problem was in the last one after kernel/initrd got loaded. Have you
tried update the uboot as the bug report suggested ?

Thanks.
