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?
A typical error looks like
Error: arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dts:252.1-18 Label or path usb_power_supply not found
FATAL ERROR: Syntax error parsing input tree
scripts/Makefile.lib:312: recipe for target 'arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dtb' failed
make[3]: *** [arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dtb] Error 1
There should be almost 100% correlation between seeing "arch/${ARCH}/boot/dts/"
in stderr and having a problem in the "make dtbs" stage.
Got it, thank you for the tips!

Fengguang
