SCSI (?) trouble, still.

    Hi,

       I've resolved that SCSI IRQ problem but still: In the old machine (a
    PIII running 2.4.1-pre something kernel), I can use my scanner and
    everything works, but when I move the AHA2940 adapter and scanner to
    the new machine (an Athlon running 2.4.5), the resulting images are
    only garbage. Everything else seems normal, i.e. I don't get any error
    messages or SCSI timeouts or such, it's just that the data returned is
    bad.

    On both machines, the scanner is the only device on the SCSI bus.

    I have tried it with a sane version compiled on the new machine, and I
    have also tried using the binaries from the old machine; both have the
    same problem.

    I am attaching a debug printout from a small color test scan. The
    "fujitsu" debug lines all seem ok. Can anyone tell me if the
    "sanei_scsi" debug lines look all right, or if you can spot some
    potential problem there.

    Any other ideas?

    Thanks
    Frederik
