    My parallel port works most of the time but occasionally it stops
    functioning and the following appears in the log:

    Dec 23 18:18:55 ozob kernel: parport0: No more nibble data (0 bytes)
    Dec 23 18:19:35 ozob last message repeated 4 times
    Dec 23 18:20:45 ozob last message repeated 7 times
    Dec 23 18:21:55 ozob last message repeated 7 times
    Dec 23 18:23:05 ozob last message repeated 7 times
    Dec 23 18:24:15 ozob last message repeated 7 times

    This requires a reboot to clear (not desireable).

    The parallel port in BIOS is set to ECP.

    The contents of /procsys/dev/parport/parport0/modes is:


    Kernel configuration:

    # Parallel port support
    # CONFIG_PARPORT_AMIGA is not set
    # CONFIG_PARPORT_MFC3 is not set
    # CONFIG_PARPORT_ATARI is not set
    # CONFIG_PARPORT_SUNBPP is not set
    # CONFIG_PARPORT_OTHER is not set


    I have an HP Color Laserjet 4500 connected to the parallel port.

    These are the boot messages:

    Thanks for any help,
