You are correct that seuss and lundmark should be identical. I rebuilt the 4.13.0-35.39 kernel in xenial to see if the issue follows the toolchain (see table below), but I failed noticed the slight differene in versions. Here's the current testing summary - next I'll rebuild 4.13.0-33.36~16.04.1 with the 5.4.0-6ubuntu1~16.04.*9* toolchain as you suggested.
