Yes. Is there a summary of the open issues somewhere? 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. -- 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.
