    Hi,
    I just saw this warning when booting:

    Uniform Multi-Platform E-IDE driver Revision: 6.31
    ide: Assuming 33MHz system bus speed for PIO modes; override with
    idebus=xx
    ALI15X3: IDE controller on PCI bus 00 dev 78
    PCI: No IRQ known for interrupt pin A of device 00:0f.0. Please try
    using pci=biosirq.
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    ALI15X3: chipset revision 193
    ALI15X3: not 100% native mode: will probe irqs later

    Booting with pci=biosirq doesn't help.
    Both test10-pre5 and test10-pre6 give this warning. test9 didn't.

    Should I just ignore it or is it really a problem?
    (My system seems to work ok)
