This is an interesting one. Apparently i have the dodgy chip in my GNote however i have flashed it twice the two different ROMs (granted they were samsung stock roms for different regions, Taiwan and UK), phone still runs great (except for a wifi bug, gets to the point that it will connect but won't receive data, again another samsung bug as my 10.1V tab has had the same issue).
I lost my lost I search at samsungdive but have to wait v long never show me my location
Thats what you get for messing around with things and playing phone god
Finally it's about time this issue got looked at. I flashed a ROM & it bricked my phone.
