Ack. ! Try http://people.freebsd.org/~kp/0001-if-Fix-panic-when-destroying-vnet-and-epair-simultan.patch Great, thanks a lot. Now I have bad news: when playing yoyo with the next-best three application jails (with all their installed stuff) it took about ten up and down's then I got this one: Fatal trap 12: page fault while in kernel mode cpuid = 1;
