    Yes, that's exactly what davem said. The corruption is happening somewhere
    in netsched/imq code that's not even part of the official kernel tree (and
    I'm told there's nobody to maintain the patch at present).

    P.S. I can post the patchset we've been using on the crashing machines
    in case someone's interested, it's reasonably short:
