yea, well, with stock kernel (and thalamus and matr1x and air kernel) everything runs fine, but i wanted to know, if there is a way to find out what exactly causes the problem with your kernel and my phone (which also might help somebody else). - raising the vol does not help that much, still some freezes from time to time (even though i'm above stock vols).
did you ever try to raise up your interval voltage?
FYI, here is the voltage sets from stock kernel of Infuse 4G (but it runs 1.2GHz):
clock / arm / int
1200 / 1300 / 1125
800 / 1200 / 1100
400 / 1050 / 1100
200 / 1000 / 1100
100 / 950 / 1100
