Have you made any adjustments to the governor, clock speed, voltages or any other tweaks? What ROM are you on? What KT747 kernel version? Are You using the kernel cleaner found in the OP before flashing? These are important details to provide before anyone can even begin to help you.

posted about it a few days ago to no avail. The kernel cleaner doesn't do anything that I don't already do but I run it for good measure. I already tried a full wipe without restoring anything and also not changing any ktweaker settings. It freezes on lock screen as well as in general on some occasions like when I try to type something and the keyboard loads, the screen will freeze. If Pandora is playing, it will continue to play until it hits the end of the track, then the music dies. Apps will crash for no apparent reason, even with data cleared. I'm at a loss
Just had a lock when I went to send a text, hit the address book link and the phone soft-rebooted (went to CM boot animation). I am running CM10.1 2-18-2013 build, kt kernel 2-8-2013. It's been with every release of KT's kernel since 12-24 until now. No other reports of issues like this on the CM thread.
