Comment 111 for bug 25931

I was able to "fix" this problem by installing all new updates.

Because I was unable to use WLAN I had to do the following steps:

1. Boot from the Ubuntu CD
2. Connecto to your WLAN (i.e. make sure that you have an internet connection)
3. Mount your linux partition (on my computer it got mounted at /media/disk)
4. Open the terminal
5. Do binding mounts
    sudo mount --bind /dev /media/disk/dev
    sudo mount --bind /proc /media/disk/proc
    sudo mount --bind /sys /media/disk/sys
6. chroot into your linux
    sudo chroot /media/disk
7. Update your system
    apt-get update
    apt-get dist-upgrade
8. Reboot

Now your system should be alive again.
