LocationManager: strange behaviour since Gingerbread update on HTC Desire HD

Since I updated my HTC Desire HD to Gingerbread (2.3.3, official update) the LocationManager isn't working correctly anymore. The android-own gps icon is blinking (searching for a fix) and when a fix was founded, the icon disappears. After some seconds the icon is blinking again and disappears again...

The strange thing is that I didn't change anything on my code an that the same code is working as expected on other devices like HTC Desire or Nexus S.

mLocationManager= (LocationManager)getSystemService(Context.LOCATION_SERVICE);
mLocationListener = new MyLocationListener();

// begin with requesting GPS
mLocationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 60000, 10, mLocationListener);

When the location functions are started in my app, I get a huge amount of messages by logcat:

I've tested some other installed apps on the HTC Desire HD like Googles MyTracks and there it is working correctly. So I really don't know why this problem only appears with my app only on a HTC Desire HD.

Thank you for reading and your help!
