    Subject2.4.1: DMA gets disabled due to irq timeout
    Hi,

    I was trying 2.4.1 kernel but under some IO load (bonnie++)
    DMA gets disabled with following messages:

    hda: timeout waiting for DMA
    ide_dmaproc: chipset supported ide_dma_timeout func only: 14
    hda: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
    hda: timeout waiting for DMA
    ide_dmaproc: chipset supported ide_dma_timeout func only: 14
    hda: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
    hda: timeout waiting for DMA
    ide_dmaproc: chipset supported ide_dma_timeout func only: 14
    hda: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
    hda: timeout waiting for DMA
    ide_dmaproc: chipset supported ide_dma_timeout func only: 14
    hda: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
    hda: DMA disabled
    ide0: reset: success

    I am wondering is there known way how to fix (workaround) this problem?

    May it be because of ServerWorks chipset (support for ServerWorks was
    compiled in)? or SMP?

    Here is except from dmesg:

    Uniform Multi-Platform E-IDE driver Revision: 6.31
    ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
    ServerWorks OSB4: IDE controller on PCI bus 00 dev 79
    ServerWorks OSB4: chipset revision 0
    ServerWorks OSB4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xd008-0xd00f, BIOS settings: hdc:pio, hdd:pio
    hda: FUJITSU MPG3307AT, ATA DISK drive
    ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
    hda: 60046560 sectors (30744 MB) w/2048KiB Cache, CHS=3737/255/63, UDMA(33)

    I will appreciate your help,
