However I did notice something else odd. The problem only occurs on bge0, the second interface bge1 does work. I grabbed the U57DIAG diagnostic boot CD from the Broadcom site, and noticed that the first interface has ASF enabled, while the second one has not. I disabled ASF by doing: = b57udiag -cmd setasf -d == And now the first interface also works properly. So there is something with the ASF stuff that conflicts with FreeBSD. The IPMI card of the system is configured to use a dedicated 3rd LAN port, and is NOT sharing bge0. But perhaps the NIC is initialized differently nevertheless when ASF firmware is enabled, and that is causing issues? Yours sincerely, Floris Bos
