[Users] Panic on FreeBSD guest with >1 CPU

Hey all! Since recently patching our hosts, I´ve been having trouble running FreeBSD guests with more than one virtual core or socket. I have managed take a screenshot of how it looks like when it panics when booting kernel, right after ACPI: http://i47.tinypic.com/2u90qrr.png I´ve tried this with similar results using 8.2-RELEASE, 8.3-RELEASE, 9.0-RELEASE and 9-STABLE. If I edit the guest to have only one virtual core or socket, it boots up without issue. Since noticing this, I´ve tried updating the packages one more time, thinking maybe it had already been fixed but no, it remains. These are the package versions I´m using: # rpm -qa | egrep '(kernel|libvirt|qemu|vdsm|seabios)' | sort -d ipxe-roms-qemu-20120328-1.gitaac9718.fc17.noarch kernel-3.6.2-4.fc17.x86_64 kernel-3.6.3-1.fc17.x86_64 kernel-3.6.7-4.fc17.x86_64 << This is the one that´s running libvirt-0.9.11.7-1.fc17.x86_64 libvirt-client-0.9.11.7-1.fc17.x86_64 libvirt-daemon-0.9.11.7-1.fc17.x86_64 libvirt-daemon-config-network-0.9.11.7-1.fc17.x86_64 libvirt-daemon-config-nwfilter-0.9.11.7-1.fc17.x86_64 libvirt-lock-sanlock-0.9.11.7-1.fc17.x86_64 libvirt-python-0.9.11.7-1.fc17.x86_64 qemu-common-1.0.1-2.fc17.x86_64 qemu-img-1.0.1-2.fc17.x86_64 qemu-kvm-1.0.1-2.fc17.x86_64 qemu-kvm-tools-1.0.1-2.fc17.x86_64 qemu-system-x86-1.0.1-2.fc17.x86_64 seabios-1.7.1-1.fc17.x86_64 seabios-bin-1.7.1-1.fc17.noarch vdsm-4.10.0-10.fc17.x86_64 vdsm-cli-4.10.0-10.fc17.noarch vdsm-python-4.10.0-10.fc17.x86_64 vdsm-xmlrpc-4.10.0-10.fc17.noarch Do you have any insights as to what the problem might be?
