I don't understand. Well, I'm not sure what the actual bug is, and it may be due to where certain code is physically located meaning that other changes since 5.2-BETA may now cause the bug to appear. When I tried to track down my problems with 5.x there were no diffs of any content between 4.x and 5.x in bios.c, but I still always got the panic on 5.x. I think it is some kind of pmap bug or other. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
