Description Bob Copeland 2009-05-13 04:01:29 UTC 
(Note I have bisected this, will follow-up in thread shortly)

From http://lkml.org/lkml/2009/5/7/157:

I have been seeing the following in 2.6.30 whenever I suspend to ram.
The power button no longer works afterwards.  I don't recall any 
problems with 2.6.29.  Anyone have any ideas before I try bisecting?

(The previous W taint is something unrelated.)
