    Hallo,
    according to linux-2.6.4/Documentation/ide.txt :
    "idex=noprobe" : do not attempt to access/use this interface
    SuSEs inofficial 2.6.4-0 kernel ( precompiled from rpm) comes with
    CONFIG_BLK_DEV_SIIMAGE=y
    CONFIG_SCSI_SATA_SIL=m

    Trying to use the sata_sil driver for my sil3112 controler I did give
    ide4=noprobe ide5=noprobe hdi=noprobe hdj=noprobe hdk=noprobe hdl=noprobe
    on the kernel commandline

    The Bootup- messages show:

    Why is the SIL3112 taken over by the siimage driver ?
    Did I misinterpret ide.txt, is ide.txt wrong or is this a bug ?

    hdi=noprobe seems to work however. The attached SATA disk doesn't show up.
    And it does show up if I leave out hdi=noprobe.

    Is there any chance to use sata_sil with that kernel configuration ?
    Or is recompiling with CONFIG_BLK_DEV_SIIMAGE=m or with siimage disabled the
    only option ?
