You will need to recompile kernel image (https://help.ubuntu.com/community/Kernel/Compile)

Based on the reply on the bugzilla tracker i assign to udev

I mail this to udev mantainers

Committed upstream, thanks!

This bug was fixed in the package udev - 175-0ubuntu1

---------------
udev (175-0ubuntu1) precise; urgency=low

  [ Loïc Minier ]
  * Update Vcs fields for precise.

  [ Steve Langasek ]
  * debian/udev.initramfs-hook: we aren't using pkill anymore, so don't put
    it in the initramfs.

  [ Martin Pitt ]
  * Unapply patches, they are not meant to be applied in the bzr branch.
  * New upstream releases 174 and 175:
    - Daemon moved to /lib/udev/udevd
    - path_id, usb_id, input_id tools are built-in commands now
    - fusectl filesystem is no longer mounted directly from udev
    - The long deprecated keys: SYSFS=, ID=, BUS= have been removed
    - The udev control socket is now created in /run/udev/control
    - The rules to create persistent network interface and cdrom link
      rules automatically in /etc/udev/rules.d/ have been disabled by
      default.
    - Support for 'udevadm trigger --type=failed, and the
      RUN{fail_event_on_error} attribute was removed.
    - Various keymap fixes (LP: #606599, #637695, #696671, #763525, #770680,
      LP: #795694)
    - Unbreak findkeyboards (LP: #881158)
    - Lots of bug fixes.
  * debian/rules: Explicitly enable persistent net/cdrom rule generator by
    default. Upstream default changed, but this seems too much a change for
    12.04 LTS.
  * Drop move-input_id-to-default-rules.patch, race-condition-on-exit: Applied
    upstream.
  * jack-detection.patch: Port to new upstream version.
  * load-fbcon.patch, use_run_tmpfs: Unfuzz.
  * debian/udev.install, debian/udev-udeb.install, debian/udev.initramfs-hook,
    debian/udev.initramfs-top, debian/udev.installer-startup,
    debian/udev.udev-finish.init, debian/udev.upstart: Update to changed
    location of udevd (/sbin → /lib/udev) and the three now builtin _id
    helpers.
  * debian/libudev0.symbols: Add new symbol from this release.
