I flashed the newest version this afternoon. I have noticed that every time it goes into sleep mode, I cant turn the screen on. I even tried plugging it in which usually wakes it up, it didnt. When I had 0.6.9, it would only do it occasionally. The only way I can reset it is to take the battery out. Then its fine. Is anyone else having this problem with the newest version?? Also, I know when you flash a newer version of the same rom your on, you just have to clear caches, does it work the same way if I wanna flash to a older version of the same rom?? Also, do we need to flash gapps every time we update the rom?? I dont remember doing it before but when I flashed this afternoon, I had no market or my contact list. I flashed gapps and it all came back.
Sleep of death -- no, I don't have that problem. Have you tried a wipe data/factory reset?
Flash to an older version - yes, you can do the same thing as upgrading.
flash gapps - yes, you should flash GAPPS every time that you flash a new version.
Not sure how to actual test this other than going into performance settings and regardless of what i set the cpu speed to, when i enable wifi it shows under current speed peaked out and remains there.
The issue according to what people have reported only occurs when you have bluetooth and wifi enabled at the same time and are using them simultaneously. I personally have never seen the issue but I also don't use a lot of BT devices at the same time that I have wifi enabled. However, with the number of people, including tickerguy, who have reported it, I'm pretty sure that it was an issue in cm7. Whether it is also an issue in cm9, we don't know for sure yet...
