Again, just >a thought... Yes, the problem other people were having with occasional panics is apparantly unrelated to the bug you found in the initialization code. It is still believed that removing PG_N fixes that problem. There should be no difference in performance in any case. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
