We initially run "make" without vmlinux, however during bisect more specific make targets will be used to speed it up. To do that it's necessary to know the regex patterns of "make dtbs" error messages, so that they can be correctly bisected. Can you give some "make dtbs" error messages or patterns? Thanks, Fengguang
