Flashed 31 last night (and 30 and 29 before it).
I am finding these issues, and after wiping very THOROUGHLY, I'm confident these issues are with CM:
1. Way too much time time taken to boot up SD Card. Scans for errors and takes a minute or more to finish.
2. LauncherPro now ForceCloses after boot-up, after which it is fine.
3. After connecting my Bluetooth, the defualt bluetooth volume is always set to minimum and it requires turning it up manually.
4. In the default browser, web pages don't scroll down completely... portrait mode is not so bad, but landscape mode will not scroll at all.
5. Not really an issue I guess, but 31 seems to be slower again... Quadrant benchmarks are consistently between 1100 - 1400 fully maxed out in Performance mode.
I feel like I'm being nit-picky, but if these issues could be addressed without creating new issues, this would otherwise be a perfect ROM!
