With recent 2.6.31-7 kernel in Karmic, this issue becomes even worse -
boot process hangs after setting up dm-crypt volume. Booting -6 kernel
works (with above workaround).

I have added linux tasks, as it seems recent kernel update makes it works.
I would like this to be milestoned for next alpha release, but I will leave the 
decision to someone else.

+ I have done a fresh install of Kubuntu Karmic on my X200s laptop. I have used 
same/similar disk layout as I use on Jaunty:
  - /boot on regular partition (/dev/sda1)
  - / on LVM volume on regular physical partition (/dev/sda3)
  - /home on LVM volume on top of dm-crypt physical volume (/dev/sda2)
  
  Karmic boot fails almost in 100% (I think boot succeeded once or twice),
  because fsck fails finding UUID of my /home partition (see attached
  /var/log/fsck/checkfs). I can easily workaround the problem by issuing
  "mount -a" (which successfully mounts /home) and "exit" the shell and
  then the boot sequence continues properly.
  
  I have attached "fdisk -l /dev/sda" and "vgdisplay -v" output. If
  anything more is needed, please let me know.
