There are no sun4v PRs open. http://wiki.freebsd.org/FreeBSD/sun4v effectively hasn't been touched since November 2006 and suggests that the only critical issue is lack of serial port support. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --WoqaC9TUMqqIOlla Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkivQ84ACgkQ/opHv/APuIdZuwCglKH8AiGskbfJXqdbFd9PVipt OeMAnA4v40rQalNO/rEi9s5fDfq/+9IQ =CDvj -----END PGP SIGNATURE----- --WoqaC9TUMqqIOlla--
