[etab3ta]

This is the output at the commands required:
enzo@pangolin:~$ cat /proc/version_signature > version.log
enzo@pangolin:~$
enzo@pangolin:~$ sudo lspci -vnvn > lspci-vnvn.log
[sudo] password for enzo:
enzo@pangolin:~$
enzo@pangolin:~$ lsb_release -rd
Description: Ubuntu precise (development branch)
Release: 12.04
enzo@pangolin:~$

From a few days everytime I boot my 12.04 find errors in the file system. After repair, Ubuntu work, but very slowly.
The boot work slowly also, about 140/150 second before find the errors(normally 20/30 sec before the login page).

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We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found.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 upgrade

If the bug still exists, change the bug status from Incomplete to New. 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.

This looks like a duplicate of bug 914319 so I am marking it as such. Please continue to track this issue at that report. Thanks.
