When the packets were dropped, there was a different sequence in the log - DISCOVER/OFFER repeated. The "normal" is that the sequence appeared correct and complete - DISCOVER/OFFER/REQUEST/ACK - or INFORM/ACK (vs. INFORM repeatedly sans ACK) as the case may be.Anyway, I'd be intersted if the switch matters here. Plus one more test: could you try to load sky2 with the parameter: "copybreak=1" (the rest as in any recent test, which gave you dmar errors; any switch). Thanks, Jarek P.
Ok - will try with and without the copybreak=1 after I'm done bisecting 2.6.33 rc5 for something unrelated (it'll take a couple of days for each unless a crash occurs in less that 48 hours).
