I think Xubuntu did an update before I couldn't start the computer anymore  
but I'm not sure.

Xubuntu 10.10 (which is Ubuntu 10.10 with XFCE FWIK).

It's a notebook that has a 128 GB Samsung SSD in it. /dev/sda1 is mounted  
at /boot. I use GRUB.

/dev/sda2 is the crypto partition which houses / and swap. Here's the  
layout:

Can't remember exactly.

Do you know how I can save the dmsetup tables to disk?
