Hi guys!! I can't resolve this problem, or i too much tired to see the solution now, since a few week i see strange output when i shoutdown, this night i spend my time to read log, and i've found that "kernel need apparmor 2.4 compatibily patch" [log]. I know that apparmor is important for security and stability inside kernel, then i googled and in fact i've found lot of post with similar problem (some link at bottom) but  nothing for my kernel version 3.4.0-030400-generic-pae , perhaps someone have my same problem or can tell me how to fix, or how to "move"?!? the problem seems to be 'cause my kernel isn't vanilla and so doesn't exist (or not yet?!?!) patch for mine (check [2] link) someone can help me please??
