I haven't, I'm still running the 1.51 kernel as I don't see any need to overclock further. I'll probably flash the 1.8 eventually just to see if my processor can do it and to say I can haha. People on XDA are saying you need to flash the 1.51 kernel before you can flash the 1.8 for some reason. Also don't forget to clear the Dalvik cache.
