Hi,
I've been hitting this panic two times now, and I thought I'd report it in the hope that someone can tell me what might be wrong. Not very long ago I bought a new ethernet card, a 3C905, exactly the same as the one I already had but this one apparently has rxcsum and txcsum. The computer is an SMP machine with two xl(4) network cards, but only xl1 has a network cable attached to it. The kernel is from August 22. I will keep the crash dump around for a while if anyone has any other requests, or would like to poke around in it. At the time of the crash there wasn't much network traffic, but I think I maybe got some bad hardware or that the xl driver is not fully MPSAFE? -- Morten Rodal
