i've had this 100% cpu bug in my freebsd vps and it's been driving me mad thinking it was me... turns out its a bug in virtio and the fbsd kernel driver is doing it.. dunno how many fbsd users are on 13.0 on arp, maybe i should report it so others aren't bit by this https://bugs.freebsd.org/bugzilla//show_bug.cgi?id=254513
