>Description:
I apologize for my inexperience in bug reporting (this is my first one).

I have just seen my server to reboot but the problem seems to be older. I found 
these log in my message files :

And the crash occurs all the day until today. Maybe a bug with the USB mass 
storage ...

Have you some advices to help me to produce better informations to understand 
this problem ?
