I had the same issue on older boxes and it went away after setting hint.hpet.0.legacy_route=1 hint.attimer.0.clock=0 hint.atrtc.0.clock=0 in /boot/loader.conf (see hpet(4)). -Karl ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to freebsd-virtualization-unsubscr...@freebsd.org -- Michael Gmelin ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to freebsd-virtualization-unsubscr...@freebsd.org
