I include his message below primarily for posterity on the bug ticket and mailing list archives. He's confirming 2.6.23 fails in the same way as well on this particular box with the two 8139too cards in it. I expect to try the older kernel versions Andrew suggested in the next few days and will report back when I have. Meanwhile, I have vague and more-or-less unfounded theory that this bug is specific to having two of the same style card in the same box. Would it be useful, assuming that I can't make an older kernel work, to try seeing if I can physically unwire one of the ethernet cards to see if the problem occurs with only one card wired up? (This may be undoable without breaking something on this tiny box, but I'm willing to have a go if folks think it might help.) ######################################################################### Date: Tue, 13 May 2008 16:40:46 +0800 To: bkuhn@ebb.org Subject: Re: (net 8139too) dual ethernet system, any reasonable network causes: NETDEV From: "Alex REDACTED" We're using an ebox 4852/4853 with debian linux kernel 2.6.23. Today during testing, we found the exact problem that you're reporting - NETDEV WATCHDOG timeouts when any reasonable network load is placed on routing between the ethernet ports. We're using the 8139too driver too, version 0.9.28. No solutions yet, we will probably look into it as time permits. Just thought you might appreciate another kernel version data point.
