It wouldn't be this same exact bug as the 4.15.0-13.14 kernel doesn't call __ptrace_may_access() when deciding to make use of IBPB while doing a task switch. It makes me wonder if you didn't accidentally reboot into the 17.10 kernel by accident (or maybe due to some post upgrade bug). Either way, please leave a comment if it happens again.
