if you're getting that many fc's id suggest burning it down and starting over. do a full wipe, (cache, dalvik, system, data,) and follow the flashing instructions.
1. flash rc3
2. boot up and give it a few minutes
3. flash the AOSP addon
4. boot up, change the DPI to 213
5. reboot, and youll be in tablet mode.
myself, and sounds like many others here, have been running it perfectly. I'm going on 8 hours, and ive only had 1fc, and it was a random 'exchange services has stopped'.
give it a try man, this rom is worth it!
