Hmmm, I'm a bit skeptical of this explanation, for the following reason.

The same kernel and source tree is on 4 identical boxes (4 P120's), and the 1 P6, and the P6 only has this problem. Swapping cards and slots doesn't fix it either, it's only on the P6.

So I'm thinking a hardware problem of somekind, but I can't imagine what. 3com cards work fine, the adaptec works fine, just the darn network card.

I've seen this same behavior and a knowledgable friend tells me it's a common bug. Claims that it expires the arp entry for the default router, so you can't talk to it from anywhere outside the subnet. A work-around is to have either a cron job that pings out of your subnet every few minutes, or just do what I do and:

% ping -i 300 <somedistanthost> >& /dev/null &

I haven't look into the kernel to see if this is the case though, but the ping does the job (as well as logging in from the console, then telneting out.)

I too have only experienced this on our one P6-200. We have several P5 machines with the SMC Ethernet (de0), and they do not exhibit this message.

Sounds like a loop-counter in the de driver code instead of a sleep().
