Some addition suggestions regarding your original E-mail. When you include the 
entire dmesg output, all of that information goes to thousands of subscribers. 
What a waste of bandwidth. If you think it is important, upload it to some 
public pastebin site and include the link. That way, only the small number of 
subscribers have to actually download it.
