As you see ukphy(4) was attached to bge2 so it may cause various issues. Is bge2 ASF/IPMI enabled interface? It seems ASF handling in bge(4) causes more trouble on recent controllers. Unfortunately disabling ASF may also trigger other problems like NMI. I believe bge(4) should always honor ASF/IMPI firmware instead of relying on hw.bge.allow_asf tunable and have to strictly follow firmware handshake sequence. Just ignoring ASF/IMPI firmware seems to confuse firmware. Unfortunately all these information is undocumented and fixing it requires real hardware access. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
