not sure if I am running mce_test correctly, but during its routine of 
testing things I do get a pause with everything, then the below shows up 
in dmesg..:

http://fpaste.org/kMRd/

seems light of a pause, then everything resumes properly(music, etc..).
Is this something that needs attention, or are these tests as extreme as 
can be, and should simply be ignored?
(Note: if there is a mce list somewhere let me know so I direct this to 
the proper people)
