What happens when you try to compile 4.8/r.10 with a Xenial .config? I'm willing to bet the problem is that the Xenial config turns on symbols and Yakkety/Zesty disable them by default. See these for further info: CONFIG_DEBUG_INFO=y CONFIG_DEBUG_INFO_REDUCED=y CONFIG_DEBUG_INFO_SPLIT=y It appears that you'll need DEBUG_INFO_REDUCED=n for kgdb to work properly.
