    Hi,
        Linux running on my new Dell-8400 computer does not recognize
    the SATA disks [No problem with the PATA drives].
    The attached log is output from 'dmesg' with '/proc/modules'
    and 'ps -Hel' appended.

    This machine has 4 disks, configured in the Intel Raid configuration
    BIOS as 3 devices, with disks on ports 0 & 2 being a raid1 pair,
    half of disks 1 & 3 also a raid1 device and the rest a raid0 device.
    The raid signatures on disk 3 have been removed [for testing].

    Ths "SATA Operation" setting in BIOS is set to "RAID Autodetect / AHCI".

    I have set symbols ATA_DEBUG and ATA_VERBOSE_DEBUG to 1 for more output
    and built a new set of modules.

    I have configured netbooting [PXE] for this machine and I can boot
    the kernel with an initrd. The only thing it currently does is loading
    usb modules for console, usb keyboard, network and starting a shell.

    Giving the command "modprobe ahci" hangs the machine.

    Using "modprobe ahci &" instead and investigating the state at that
    time leads me to suspect ata_dev_identify() waits for an interrupt that
    is not occuring.

    The attached '/proc/modules' and 'ps -Hel' are from this environment.

    Please, can someone help me debugging this further, what other info
    would be usefull, are there other experiments that can provide new
    insights into this problem.....
