Zach, thanks for the feedback. Since we still struggle to recreate this on our side is there a chance that you could test kernels from [1] to help spotting which version bump exactly it was?
Going further we might even need to bisect things, but one step at a time. I'd not want to put this on you (or the others), but if it continues not to trigger for us we might have to. It is now clear that multiple people see this dependent on the kernel, adding a kernel task for it. Maybe they have heard about similar issue on other bugs?

I tracked it down to the Guest OS attempting to use the Network Connection, and if I disabled the virtual NIC for the VM, everything runs OK (albeit without a working network connection for the Guest OS). Note that I'm just using the built in virtual network called "default" that get's installed by default and uses NAT forwarding. I believe the problem is related to AppArmor, as I noticed some errors present in various log files. Unfortunately, due to a time critical project I had to roll back to Ubuntu 19.04 and didn't capture any of the log files. I did, however, find another user on Reddit with the exact same problems that I encountered and he agreed to let me post the log files. Here are what are think are the relevant pieces from the log files: =================================================================== Oct 22 22:59:23 brian-pc dnsmasq[2178]: exiting on receipt of SIGTERM Oct 22 22:59:23 brian-pc kernel: [ 67.001284] device virbr0-nic left promiscuous mode Oct 22 22:59:23 brian-pc kernel: [ 67.001298] virbr0: port 1(virbr0-nic) entered disabled state Oct 22 22:59:23 brian-pc NetworkManager[3557]: <info> [1571799563.3862] device (virbr0-nic): released from master device virbr0 Oct 22 22:59:23 brian-pc gnome-shell[4401]: Removing a network device that was not added Oct 22 22:59:23 brian-pc gnome-shell[2463]: Removing a network device that was not added Oct 22 22:59:23 brian-pc avahi-daemon[1621]: Interface virbr0.IPv4 no longer relevant for mDNS.
