idea, anyway, in my experience.

I'll go down the Kubuntu 19.10 path first and if that doesn't solve things
then I was thinking I'll look for an audio production distro that has
real-time in it, Ubuntu based or not, and give that a try. I think
PlanetCCRMA is still out there although not generally looking forward to
going back to Fedora.

Hi,
   Short version: Problems with my Scarlett 2i2 3rd gen are apparently
solved updating to Kubuntu 19.10.

   The kernel appears to be based on 5.3.18. I've run with no networking,
wired and wireless networking and all appear to be fine. I ran a Mixbus
session looping for about 8 hours, at least 1 hour on battery, moving
around my house carrying the Scarlett with the machine, running
Chrome/YouTube/Netflix and nothing caused the audio to fail as it had
earlier. I didn't have time to do any recording but I figure this level of
operation at least confirms the Reddit post,

   I didn't get the chance to try m.eik's hwe-18.04 path as I had already
moved to 19.10. I'm creating a Kubuntu 18.04 LTS VM just to learn the
commands, both the hwe-18.04 command and installing a kernel from the
provided link using (I assume for now) "sudo dpkg --install ***) However at
this point it doesn't look like I need more than the standard kernel.

   Thanks to everyone for the help getting this far. I do appreciate it
greatly.

Cheers,
Mark
