That line should go on, it works.
However, it seems that something is still broken w. sleep.  
Yesterday, 1 out of 2 attempts to sleep,wake failed. The machine froze, with 
an apparent race (the cpu heated up).
Today, I could get an OOPS in 1 of 3 attempts to sleep. I give (early) the 
decoded info (I have no ksyms!? ). Perhaps you could make out sth of the 
trace..
