    James,

    Below is what I get WHEN IT BOOTS. There are also a couple more logs and
    notes in between.

    Even with the patch that you posted last night something still isn't
    quite right. Notice in the output below that the faster drive is setup
    at 80MB/s instead of 160MB/s. It's like going back to the days before
    U160 stuff worked properly :)

    And then finally the output this morning of booting 2.6.12-rc2 (with RT
    patches applied, which is irrelevant to this conversation). This one
    does properly setup all of the drives.
