[T-Mobile Samsung Galaxy S II SGH-T989] UltimaniumX:
Here is the logcat that I ran for about 2 minutes. It replicates the issue that multiple users are having with skipped frames. I cut out a lot of log because there's well over 16000 lines of information. If you want the whole log, I can attach it.
