Thanks for taking this on! The only current consumer of the bounce pages code on alpha is the UP1000 platform, all other platforms use scatter/gather DMA for address limited (ie, ISA), devices. I have a UP1000, but its currently in a totally hosed state. I'll need to install 5.x on it, and build my way current. I might not have time to do that for a while. I guess what I'm trying to say is: "don't hold your breath waiting for testers" ;) Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the messagehelp
