    (Though I must confess, that in spite of my Master degree in Electrical
    Engineering and extensive HW experience, I can not for the life of me
    understand how you can find it more likely to be cables (that work fine
    with other controllers), disks (that also work fine with other
    controllers) or the power-supply (that also works fine with exactly the
    same things connected to it) rather than the motherboard's
    SATA-controller (that is the item that actually is reported to fail in
    the first place). - Sure, I'm well aware that sometimes the combination
    of HW matters, but to my experience we're normally not talking about
    "dumb" stuff like cables and PSU if that is the issue.)

    Anyway, I have just changed to the other (identical) motherboard, and
    things are running just fine at the moment...
    I'll let you know if they start acting up (as they did before). If not I
    guess the fault was with the motherboard and not the driver - Guess
    we'll know pretty soon...

    Thanks for all your effort, gents, let's hope it all works now!
