problem with wakeup from sleep by the incoming call

[Eduard Budulea]

Hi I have the debian install to a neo freerunner (A6).
last debian update was a week ago.
the sleep/wakeup works ok, except this scenario:
I put my neo to sleep and a call comes, the device wakes ok and I answer
the call.
after that no matter if I close or the other guy closes the system will
no longer enter in sleep.
also I cannot use the gsm anymore (make or receive calls).
