Just my two-cents: I noticed the same bug on both Ubuntu workstation as well as Kubuntu, but my Ubuntu server does not seem to have the same problem. All three are running 18.04 with the 4.15.0.36 kernel.
I tested all three when they were freshly installed (kernel 4.15.0-29-generic) and after upgrade (kernel 5.15.0-29-generic). I tried three scenarios (none of them used 'numdummies'): 1. Add "dummy" module to /etc/modules 2. Add "dummy" module to /etc/modules-load.d/dummy.conf 3. Add a dummy device with /etc/systemd/network/01-dummy0.netdev All three scenarios worked on ubuntu server, but none of them on the desktops, even though the dummy module was listed in lsmod. I wish I had time to troubleshoot more, but I'm just investigating a possible switch from fedora to Ubuntu, and thinks are not looking too good for ubuntu... Five months into their supposed LTS release and several packages I rely on cannot be installed because it does not support 18.04, and now this... Anyway, just thought I'd mention the working server...
