Hello everyone, I just wanted to report that I too had this problem (sporadic hangs of the vio0-Interface) with 5.5-stable/amd64 in a KVM-VM. I tried the solution described by Philip Guenther and voilá, the problems are gone. I did no tests with regard to the performance, it seems alright. $ dmesg |grep vio vio0 at virtio0: RingEventIdx disabled by UKC: address <some address> Thanks and have a nice day, Christoph
