I think I will stop causing spam to -hackers over this. I had been using 3.1-stable's boot1/boot2 with the 4.0 boot loader (and assumed it was OK, I thought once /boot/loader took over, it was working). I will pound on this myself for awhile and see where it goes. I would like to make the request that the KVA changes be brought back into the -stable kerenel :) -- David Cross To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
