    Unhappy Re: Boot Problems udevadm trigger

    I installed the last recommended updates, which some involve udev,
    and reboot failed with this same message. There was no power failure. I reloaded my system from a backup, boot went fine, installed only the security updates, reboot is ok.

    I would say there is a bug within this last - september 2 ? - batch of
    updated packages. Since they are only recommended, I will wait a bit
    before trying to install them again.

    In order to avoid boot to stop with "udevadm trigger is not permitted ..."
    after installing the last recommended updates for 10.04, as many
    people have suffered, I suggest :

    - install updates with Update Manager as usual

    - DO NOT accept to reboot right now

    - as root :

    # cd /boot
    # sudo update-initramfs -u -k 2.6.32-24-386
    # sudo update-initramfs -u -k 2.6.32-24-generic

    - reboot

    Worked fine for me.

    Cheers !
