Andaram mechendo em muitas coisas , como o 7.1 esta em beta nao encontrei a documentação do 7-stable , mas vi que o mesmo esta descrito no current.
This section describes the most user-visible new or changed features in FreeBSD since 7.0-RELEASE. In general, changes described here are unique to the 8-CURRENT branch unless specifically marked as MERGED features. [amd64] The FreeBSD kernel now has support for large memory page mappings (“superpages”). Só no 8 [amd64, i386, ia64, powerpc] The ULE scheduler is now the default process scheduler in GENERIC kernels. [MERGED] ULE default [amd64, i386] The BTX kernel used by the boot loader has been changed to invoke BIOS routines from real mode. This change makes it possible to boot FreeBSD from USB devices. [MERGED] ou seja pode ser instalado direto no pendrive, hummmm A bug in TCP options padding, where the wrong padding bytes were used, has been fixed. [MERGED] Sera que esse problema é o seu ? http://www.freebsd.org/relnotes/CURRENT/relnotes/new.html Não sei se isso foi resolvido , mas em todo caso isso mereceria um send-pr []'s Em Ter, 2008-09-30 às 11:09 +0000, João Paulo Just escreveu: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Olá, lista. > > Decidi iniciar outra thread porque a antiga já está bem atrás.
