Ive recently rooted and am currently trying a Siyah kernel on GB 2.3.6. I had also downloaded voltage control but the governor would default back to ondemand after a reboot. I thought maybe something was conflicting somewhere so uninstalled Voltage Control and downloaded Setcpu which I had used previously on my Desire. However Im getting the same problem - setting Smartassv2 and specifying run at boot, but it always resorts to Ondemand. On a probably unrelated issue Im finding if I leave the phone idle, off-charge for as few hours it fails to wake up from deep sleep despite having the min speed set to 200. Any clues guys ?
