Which OS/version? There is a bug in auto negotiation order in some
PHY drivers based on FreeBSD (now fixed there) that affects cisco
3550 and maybe it also affects others.. (actually the problem only
happens with a combination of a bug in the PHY driver and a cisco
bug).  http://www.freebsd.org/cgi/query-pr.cgi?pr=92599
