Yes, I know this is still happening. I also have pretty good data now that its a bogus problem, meaning due to scheduling issues the watchdog does not get reset even though the system is just fine as far as transmit descriptors is concerned. I have a patch that detects this and keeps the watchdog from erroneously resetting you, it has been running on my test system for days now without problems. Jack On 11/2/06, Patrick M.
