That's a question for the people over at Ubuntu. Upstream people like 
the ones on this mailing list generally don't do distribution support. 
Most of them have no idea what Ubuntu did to their kernel, and which 
updates they did and didn't pull into their tree. It's not their job to 
try and debug problems they could well have already solved a year ago; 
that's just a waste of developers' time. If Ubuntu decides to patch up 
and ship an outdated kernel, they get to take responsibility for it.
Meanwhile, my well-meant advice stands: try an up-to-date kernel. If the 
problem persists, you can file a bug and get a developers' attention. If 
the problem goes away but you really really want to keep running 
Ubuntu's 4.15.0 kernel branch, you can persuade Ubuntu to pull relevant 
fixes into their 4.15.0 branch and release an update.
