Hi Kevin,
			After following your instructions, setting  
CONFIG_OMAP_RESET_CLOCKS, and applying all the 204 omap-pm patches, I  
don't get any more error messages on the console. So this is a very  
big improvement since I started incorporating the omap-pm patches for  
my android-2.6.29 port to the overo platform.

Now there is only one issue left, which is you need to press the  
touchscreen for a long time (around 3 secs) for it to get the system  
to resume. There are no error messages now, but because it take a long  
time to wake up from suspend mode, it gives the impression that the  
system is un-responsive or stuck in suspend mode. Sometimes it doesnt  
come out of suspend mode at all.

Here is the output from the console window:
