Hi Kevin,
  I get hangs after boot on beagle with latest PM tree i have  
quite a
few scripts that run on boot.

  have you seen this before?

I have not, but I believe Koen has see something similar.  I've  
mainly
been testing just a minimal rootfs and a minimal set of drivers on
Beagle so I can hit full-chip off in idle.

It would help if you could desribe your setup in more detail.  What
kernel config are you using, what rootfs are you using?  Does it hang
in the same spot every time?  If so, what is going on when it hangs?
Have you written anything to any of the /sys/power/* files?

Just a thought, do you still see these problems when using the CPUfreq
performance governor instead of the ondemand governor?

It could be pointing to some bugs in the switching of operating  
points.

Speaking of operating points, is there a reason why cpufreq only goes  
to 550MHz? It's disappointing that omap3 gets marketed with "600MHz",  
but that TI won't let it run at that speed with their cpufreq drivers.

regards,

Koen
