Ok, I can add some more information. This has happened 7 times now. The trace is always exactly the same. The only change we have made was adding a second de ethernet card, and routing all nfs traffic over it. The reason being that NFS was very slow over our existing really really busy local 10MB ethernet. All NFS now goes over an 100MB ethernet dedicated to just NFS. Is this some timings thing perhaps then, possibly annoyed further by an SMP kernel? (ok, honestly, there was another change as well, we switched to a PCI VGA card instead of an ISA one. Another machine was out of PCI slots, and we needed to add another card, so we swapped them, I doubt that has anything to do with this, but I'm putting it out in the open now. :) ) Since this is becoming easily reproducable, can someone tell me what to do the next time it crashes, and I'll do it.
