The debug symbols are on for all of them, and gdb *does* load the symbols. I have a suspicion that KASLR that was introduced around 4.7 might be the culprit here. CONFIG_RANDOMIZE_MEMORY is an option that's not present in the Xenial config. Anyone here has attached kgdb to 4.8/4.10? Thanks, Kamran.
