The "DebuggingUdev" page has been changed by serge-hallyn:
http://wiki.ubuntu.com/DebuggingUdev?action=diff&rev1=8&rev2=9

   * To see the actions udevd is taking, you can run it in verbose debug mode:
    * sudo pkill udevd
    * sudo udevd --debug-trace --verbose --suppress-syslog
+  * To get more debug info from udev,
+   * edit /usr/share/initramfs-tools/scripts/init-top/udev, and change the line starting udev by adding --debug and sending stdout and stderr into a file under/dev/.initramfs. For instance:
+ 
+     /sbin/udevd --daemon --debug --resolve-names=never > /dev/.initramfs/udev.out 2>&1
+   * then run sudo update-initramfs -k all -u
+   * After reboot, /dev/.initramfs/udev.out will have the udev debug info.
+
