Title:
  2.6.32-26 unbootable: does not find root file system

Status in “udev” package in Ubuntu:
  Fix Released
Status in “udev” source package in Lucid:
  Fix Released
Status in “udev” source package in Maverick:
  Fix Released

Bug description:
  When trying to boot 2.6.32-26, the following error occurs:

  udevadm trigger is not permitted while udev is unconfigured.
  Gave up waiting for root device.
  /.. etc ../
  ALERT! /dev/disk/by-uuid/0927db9a-0528-49c5-bdc5-ff3d5a9eb9c5 does not exist. Dropping to a shell!

  2.6.32-25 boots fine.

  SRU TEST CASE:
  --------------
  This is a somewhat synthetic, but IMHO sufficient test case:

  - Pretend that udev is currently being upgraded:
  sudo /var/lib/dpkg/info/udev.preinst upgrade `dpkg-query -W -f '${Version}' udev`

  - Now update initramfs:
  sudo update-initramfs -u

  If you do this in a VM and can apply a previous snapshot, or are able
  to boot an older kernel, then you can reboot now and confirm that the
  initramfs is broken. With the fixed package this should produce a
  working initramfs. If you don't want to reboot, then you can just try

     gzip -cd /boot/initrd.img-`uname -r` | cpio -i --to-stdout
  sbin/udevadm | file -

  A working initramfs has an "ELF LSB shared object", a broken initramfs
  has a POSIX shell script (the wrapper).

  - Finally, finish the fake udev upgrade:
  sudo /var/lib/dpkg/info/udev.postinst configure `dpkg-query -W -f '${Version}' udev`
