May 1 08:29:38 alpha kernel: em0: watchdog timeout -- resetting May 1 08:29:38 alpha kernel: em0: link state changed to DOWN May 1 08:29:41 alpha kernel: em0: link state changed to UP I've gone and added the DEVICE_POLLING option in the kernel, but this doesn't seem to help. The problem only seems to happen during the hours that my users would be hitting this box, so it really gets noticed when those 3 seconds go by. And yes, it's almost always a 3 second drop on the interface. Is there anything I can do to prevent this from happening? I saw mention of a firmware update I might try, but haven't been able to locate the file in question. Thanks, -- "When you come to a fork in the road....Take it" - Yogi Berra
