4.14.xx is not a supported Ubuntu kernel. I'm not sure where you pulled that kernel from, but it is not supportable.
At this point all Supported Ubuntu kernels and mainline 4.15+ have this fix.
@EVERYONE ELSE
If you think you are hitting this issue and are running the latest supported kernels, you are likely hitting a different issue, and should be opening a new bug. Please stop resurrecting this bug.
