My N900 froze 6-7 out of 10 calls i recieved. On the way up from my pocket or table etc. it went into landscape for a short second and just struggled to get back into portrait and it was here it froze and became unresponsive so lost the call. This happend with a freshly flsshed phone, with it running powrr kernel set at 1150 and with power kernel(1150)/CSSU installed. The N900 does alot of things great just not the phone call part.
