    Ubuntu 18.04 very slow boot in dual boot

    I have recently installed Ubuntu 18.04 beside Windows 10 and the problem is Ubuntu boot takes very long time comparing Windows.
    It seems there are big gaps here in my boot log

    Code:
    [    9.918120] ppdev: user-space parallel port driver
    [   32.941450] (NULL device *): hwmon_device_register() is deprecated. Please convert the driver to use hwmon_device_register_with_info().
    and here

    Code:
    [   47.198274] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready
    [   58.801534] rfkill: input handler disabled
    [   70.037871] ahci 0000:00:17.0: port does not support device sleep
    and many errors here

    Code:

    How old is system? Or do you really have a parallel port?
    If your UEFI/BIOS had hardware listed that does not exist, it can then write that into available hardware for operating system. Then system has to time out as it cannot find it. Make sure settings in UEFI/BIOS are correct.

    What brand/model system?
    What video card/chip?

    Are you using IPv6?
    I do not know wireless issues, but best to run script from sticky threads in wireless sub-forum and post thread in that forum.

    Most issues with ACPI can be ignored.

    Re: Ubuntu 18.04 very slow boot in dual boot

    The specifications of my system are: Asus fx570UD core i7/ nvidia GTX 1050/ 12GB RAM (2019)
    Actually I don't know anything about parallel port. How can I check my UEFI/BIOS settings are correct?
    And yes, my IPv6 is enabled.

    Have you updated UEFI from Asus to latest version? May just be something in UEFI?

    Your UEFI has multiple tabs.
    Check them and see if somewhere you have a setting for parallel port enabled.
    I have not seen that in my system, but do have USB ports that need to be set to allow boot, enable keyboard & mouse, & allow full support settings.

    Have you installed nVidia driver?

    Issues often common across similar models by vendor.

    Actually I don't have parallel port on my system.
    I downloaded and updated my UEFI right now but it didn't help.
    Yes, I have installed nvidia driver but because it was draining my battery I disabled it and I'm using my intel graphics.

    1.3 says it is a combined port. combined serial/parallel port/floppy controller.

    https://www.infradead.org/~mchehab/r...n/PCI/pci.html

    So perhaps some other device is incorrect?

    Everything else related is CNC controller using parallel port errors.
