    I've installed Red Hat 7.1 distribution on my PC (with kernel 2.4.2-2 as
    Tim Waugh told me to). I've got a Oxford PCI card, that at first was not
    supported by parport's driver. I load parport_pc module just after
    installing this new distribution, and it works fine. Of course it didn't
    find my card nor made my card works. I try installing the patch I found
    in Tim's page to give support to this card. But now when I call modprobe
    in order to load the module, the computer freezes down (the keyboard and
    the mouse are blocked, and I have to restart it manually).

    In dmessg I've found this:

    request_module[parport_lowlevel]: Root fs not mounted
    lp: driver loaded but no devices found
    ...
    ppdev: user-space parallel port driver

    I have installed the kudzu's application. At boot time, when kudzu is
    called it freeze the computer down too. It seems that it recognize the
    card and try to load parport_pc module and then the computer comes to a
    "funny" freeze down.

    When I make:

    Could somebody help me? I need to put this card to work. Thanks in advance.
    If you need some other piece of information just tell me.
