With regards to xenial I jumped to conclusion to quick. The drops in connectivity were these easily recoverable ones, so I've looked at the generated assembly, and I don't see the extra load that is the cause of trouble. I would still prefer to have this fixed, because the compiler is free to generate broken code, it just does not in this particular case, but it is up to you. Sorry for the noise.
