Both your controller and drive are NOT the ones with m15w quirk.  My 
first suspects are bad cabling and/or bad controller.  Is the controller 
on board? or is it a discrete card?  Can you verify that earlier kernel 
doesn't show the error?  Do you happen to have another harddrive (maybe 
from a different manufacturer) which can be hooked to the controller and 
tested?

AFAICS, your problem doesn't seem to be m15w related.  In the past, we 
saw some cheap/flakey 3112 controllers which fail from time to time. 
libata sometimes fails to recover from such failures.  This might be 
what you're seeing.
