Dear Joseph, Unfortunately I am a Linux newbie. This means that I do not even know what you mean by "upstream kernel". I do know that when I tried Ubuntu MATE 18.10 that after three days of error messaged I went back to 18.04. I am still trying to recover data from the initial 18.04 total meltdown (I was not even able to boot). After installing different versions of Ubuntu three times in one week, I am leery of trying some method I do not know to try an "upstream kernel".
I only send in the bug reports to help the developers fix their bugs - as opposed to John Dominique Wernier's technique of not including the bugs in first place. I do know that Ubuntu MATE Artful Ardvark and Bionic Beaver both had this problem. Maybe its like the Unix limitation of only allowing 125 file handles or yacc only allowing 425 productions - the program limiting the size of a resource because he does not keep up with the size of modern computers. (i.e. Word6 limited to files smaller than 50MB in machines with 1GB RAM.) I also know that 18.04 is extremely sluggish with a 6TB external drive mounted (fortunately I did not buy the 8TB drive). If there is something I can try without having to completely re-install my OS and all applications, please let me know. I want to help.
