    Does this still happen with 2.6.23? If so, please post boot log. Thanks.

    No it does not.

    I have nearly the same setup (ASUS P5W-DH-Deluxe, Core2, 2GB RAM, 3
    SATA and 2IDE)

    And a "dmesg | grep irqpoll does not show up with results.

    dmsg | grep 23 comes up with:
    wifi0: Atheros 5212: mem=0xeb9f0000, irq=23

    And I no longer use IRQPOLL (I dropped it somwhere between 2.6.22.?
    and 2.6.23) as Kernel option.
    kernel (hd0,0)/vmlinuz root=/dev/sda3 video=nvidiafb:1280x1024-32@85,mtrr,ywrap

    All SATA Ports are working (except the the PMP... it "works" but I
    would not recomment usign it right now because of these bugs:

    Built and booted already twice, and so far, no problem anymore.
    I'll continue to watch this carefully, and will report any problem that could
    be related to this.

    Paul
