Sometimes you just get a bad download or bad flash with these new kernels. Anyone I have seen here at AC or over at XDA who has had minor problems like yours has cleared up the problem by flashing the kernel again. I've even seen people who have had to flash one of the new kernels 3 or 4 times before they got it to work. Just remember that these kernels were compiled from the Froyo source for the Mesmerize. While the Fascinate and the Mesmerize do have the same Samsung model number, they are still technically different phones. I have not heard or read of anyone experiencing any serious problems or damage as a result of flashing these kernels. It just take more than one try to get some of them to really take with your set up. Good thing is we have quite a few to choose from, so if you want to try different ones out until you find the one that works best for you. Things will be MUCH better when the Fascinate source is finally dropped. Right now we are just getting a taste of what is to come. Enjoy.
