I have tweaked some kernel message generaters to be more line based.
We had issues with CAM attached devices print out parts separately
and then get intermixed a lot.  So I modified them to print them as
one line.  Then they didn't seem to get intermixed.  This doesn't solve
the overall problem, but if messages are done more this way then 
it helps.

Thanks,
