    Hmm, strange. My PCI-Mode is (Any), I have APIC enabled
    CONFIG_X86_GOOD_APIC=y
    CONFIG_X86_UP_IOAPIC=y
    CONFIG_X86_IO_APIC=y
    CONFIG_X86_LOCAL_APIC=y

    And I use SCSI.
    I do not have any Problems. Do you have these Problems under heavy
    load, or when your machine is idle?

    Hmm. hdparm -d1 should AFAIK always speedup your IDE-HD
    I have about 6MB/s without and about 26 MB/s using DMA

    Dont know. Try to find out e.g. with xosview, which shows you
