I just flashed 2.1 (yeah yeah, I know, I finally gave in and re-rooted) and Pete's bugless beast 0.9 and I have not had any problems yet. I believe this is how a rom should be, I am really feelin' how you can do switches, and commands from the terminal emulator. I haven't flashed any kernals or anything. I'm guessing if I do, that's where the FC's and errors will come into play. But at this time, the stock bugless beast 0.9 is in fact, bugless.
