Ah interesting. I have only seen wakeup on USB cable removal so maybe 
the "modem wakeup interrupt" in dmesg is just a red herring?

Regarding my suspend/resume issue:
	- Your addition of "suspend" to the i2c s3c driver has a possible NULL 
dereference but we don't hit that.
	- the i2c s3c driver is resumed before the pcf50633
	- It is hanging in __reg_write even before the _xfer of the i2c s3c is 
getting called (which means i2c_transfer is not called) which can't be...
	- I enabled the CRC on the RAM and know I stopped crashing on me... so it 
might be a timing issue?
