There is no COMPLETELY stable rom other than one you will get from an official OTA update. Your best bet will be to completely wipe the phone and update it to 2.2 by following this guide [Howto] Get to ED01 (Official Froyo) Quickly - xda-developers
And if you still have issues with the phone while running the official update, call verizon and get a replacement.
