I'm not seeing that here... I just scp a new kernel into the vm, install it, and run shutdown -r now which drops bhyve back to loader, and loads the new kernel... I've been doing this quite successfully over the last few months... I am running a month old HEAD though... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
