I'm running CM7.1 with the stock kernel (switching to last Tiamat kernel now). 1. It's been pretty buggy for me. I'm going to reflash CM7.1 to make sure that I just didn't have a buggy download. What do I need to wipe before reflashing? Please note: I am not flashing a NEW ROM. I think that I don't need to wipe system data and other areas, just cache and dalvik cache. Can anyone confirm? 2. Like I said, CM7.1 has been pretty buggy for me. I go to ROM Manager and fix permissions at least once a week and there are TONS of permissions that need to be fixed. I didn't seem to have this many repairs when I was running stock Sense (rooted). How often should I need to refresh my permissions?
