Answer to your question is yes. But you might want to be a little more specific as to what is it you would like to find out. –  Karlson May 15 '13 at 15:16

It says libafs (which I assume is the AFS filesystem) all over it, why do you think its hardware? –  derobert May 15 '13 at 16:09
    
@Karlson Wild guess: he probably wants to know why that error is happening –  Michael Mrozek May 15 '13 at 18:31
    
@MichaelMrozek I would have guessed the same but I'd prefer to remove the guessing as much as possible. –  Karlson May 15 '13 at 18:38
