I assume you should be able to configure the NIC thru IPMI (quote from Google-found thread: ... "go to ipmi panel and choose "share" for "Lan Interface" ...). Btw, after you finished resolving the issue and collecting facts, please consider filing a Problem Report with FreeBSD - that device hint disabling em0 and bringing down both em0 and em1 interfaces should be looked at by devs, I guess - after all, they should be two independent net ports, as they have two distinct MACs. I believe you said em0 is LAN, and em1 is IPMI. jb
