well, i am not 100% sure, but i think indeed it is qi -- not at least  
because it
a) does less on wakeup (might be wrong here)
b) is configurable to print considerable less messages while resuming,  
those print outs take a lot of time

additionally the recently mentioned debugfs hack _seems_to improve things.

i tested a bit yesterday with and without the debugfs hack (only 6,7  
calls) and with the debugfs hack, one ring was enough. the second ring the  
caller heard was the first one the fr made.
w/ the hack it took usually two or sometimes three (which i knew from  
before already).
