It also failed to reboot automatically.. Is your problem on -CURRENT and amd64? At some point there has been a problem with PAT support (and tlb_shootdowns() could lead to a livelock hanging forever, leading to such a bug) but I expect it is fixed now. Can you try with a fresh new -CURRENT if any? Thanks, Attilio -- Peace can only be achieved by understanding - A. Einstein
