I've had this behavior also with Intel Pro 1000 cards using the em driver. I picked up a lot of 4 of them off ebay and never figured out if it was a driver problem or faulty hardware. I went back to FreeNAS on that same box (7.2-RELEASE-p4) and it seems ok except my Netgear gigabit switch also died so I'm currently plugged into a 100Mbps switch. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Current plan is to purchase another variety of gigabit card to see if it is specific to the intel card. If memory serves, I think there may have been some traffic about something like this on the -CURRENT list. You might look/search there and see if it sounds similar. If it seems like it might be the same thing, look for an MFC back to -STABLE. Sometimes the fix for very a specific item which has been addressed is to take a system to -STABLE in order to obtain the fixed bits. Research and confirm first, before considering such an update. My policy on -STABLE in the past is I only think about going there for a very narrow and specific situation where I know I have a problem that the devs have seen, analyzed, and fixed, with subsequent MFC. Something else too - if you can disable the vr and the USB chips completely, it might provide a data point. IRQ sharing is supposed to work well, and it is something that may be eliminated from the scenario easily if you do not need these things. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
