system hangs during boot with: "udevadm waiting for the event queue"
  • TotoetsasoeurTotoetsasoeur November 2009
    Hi,

    Yesterday I used my system as usual without any problem.

    Today it is impossible to boot it. It waits forever during boot with the following message:


    udevadm waiting for the event queue to finish...


    Actually, I had to boot on CDlive to access the forum.

    I am stuck here and need urgently your help.
    Thanks

    Can you change this line "udevadm settle" in "/etc/init.d/rcS" to "udevadm settle --timeout=10" ?

    If that doesn't work, you can comment out this line "udevadm settle" and reboot. let me know.

    As suggested, I changed in /etc/init.d/rcS the line:

    udevadm settle


    and added --timeout = 10:

    udevadm settle --timeout = 10


    => KO => the system still hangs when booting.

    Then I commented the line as following:

    ....
    if [ "$UDEV" = "yes" ]; then
    echo -n "Starting udev daemon..."
    /sbin/udevd --daemon
    status
    echo -n "Udevadm requesting events from the Kernel..."
    udevadm trigger
    status
    echo -n "Udevadm waiting for the event queue to finish..."
    #udevadm settle --timeout = 10
    status
    echo "/sbin/udevd" > /proc/sys/kernel/hotplug
    fi
    ...


    => OK => it works. :-)

    Then what am I supposed to do. Leave the line commented or something else?

    Waiting for your comments.

    Recharge and Upgrade the system again. See if after uncommenting udevadm line, boot works. This is known problem with udev but no satisfactory answer.

    Moreover, I think you should not put spaces after timeout, e.g., it should be "udevadm settle --timeout=10"

    --timeout 10
    or
    --timeout=10
    as suggested, as the equals sign and '10' will be given as separate arguments rather than being part of the same one!

    I recharged and upgraded => ok. Now it works as before, but for how long?

    I keep your trick about the timeout parameter just in case thing goes wrong again.

    Thanks for your help. ;)
