Bug Description
Since 3.2.0-21 the kernel does not locate my hard drive. Consequently, the kernel cannot locate the system partition, which results in a kernel panic -- unable to mount root filesystem.
The suggested valid boot devices following this error include only my CD-ROM drive (sr0).
Kernel 3.2.0-20 boots fine.
Kernel 3.2.0-22 suffers the same problem as 3.2.0-21.
Please let me know if I can supply any further/more specific information.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
You can update to the latest development kernel by simply running the following commands in a terminal window:
sudo apt-get update
sudo apt-get dist-upgrade
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.
Thank you for your help, we really do appreciate it.
