    Well, I upgraded to the latest driver today and the problem persists.
    (By the way, upgrading via the driver source does also upgrade the
    firmware and BIOS.) I spoke to 3Ware support. They seemed familiar
    with the problem but blamed it on Red Hat's Kernels. They then referred
    me to some performance tuning appnotes which I tried with no success.

    I guess I'm off to buy a new card this afternoon - probably LSI or Adaptec.
