    SubjectRe: CONFIG_BLK_DEV_SL82C105 should not be PPC/ARM specific
    From
    Date
    That patch (plus bludgeoning the config) certainly *works* on this
    chipset, but it doesn't get DMA support; logs follow. If I run hdparm
    to put it into using_dma mode, and then try to access it, using_dma
    mode gets turned off after some delay...

    idebus=xx

    PCI: No IRQ known for interrupt pin A of device 00:02.0. Probably
    buggy MP table.
