hotplugx governor makes my phone freeze on this... hear i was thinking it was the overclock
The only difference between hotplug and hotplugx is how soon the 2nd core is turned on or off, so I don't think its the problem. Are you using setcpu? Once you've flashed an OC, go to setcpu to make sure the values for the clock speed are correct. Sometimes it sets the max to 300 so you have to adjust it and reboot.
