There are autoneg problems with some devices (e.g. cat3550 which advertises a media type it can't actually handle which causes a problem when coupled with a bug present in quite a few OS), but AIUI in those cases it still does the same (though wrong) thing each time. Have you tried a different PSU yet? If you don't have one handy, try removing devices (e.g. your 2-port card?) to lower the load and see if that helps. Especially if you have the PSU type that people have been reporting problems with on this list... _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
