The Cisco tool has trouble with both kernels. openconnect has so far not had problems with 4.16rc6 from the mainline PPA. So it is only Bionic's 4.15 so far. Not tested with mainline PPA 4.15, but I can if that makes sense. I am guessing it is a heisenbug, but I might be wrong.
I posted to the openconnect mailing list[1], but no answer yet.
