Dear Joseph, I have no idea about the patch/fix kernel team / process, etc. I'm just a regular user of linux since 20 years ;) I googled the problem, found a fix and asking ubuntu to include this fix in its kernel. Don't ask me to open another ticket at another system. I don't care. Too much effort. This should work by default in 2016. I might just buy another type of this thing, that's easier ;)
