After few more test I can say that only FreeBSD 7 amd64 is affected. It 
just panic and freeze while trying to boot on this server.
FreeBSD 6.2-stable amd64/i386 and FreeBSD 7 i386 boot without problems, 
so it seems that there is a regression in FreeBSD 7 amd64.

I hope this can be fixed before 7.0 Release.
