(In reply to Bruce Rogers from comment #18) > I'm finding that something in kvm is broken on this machine back to v4.16.0. > It seems people don't use this old hardware very much for kvm virtualization! For me, exploring http://download.opensuse.org/history pays dividends. I find that the 4.18.7-1.5 kernel (in TW 20180917) works, but the 4.18.8-1.3 kernel (in TW 20180919) doesn't work. Hope this ties it down to only a few kernel changes !
