I have a strange problem with under/overclocking: Always when I try another profile than default (starving and XLV tested) the phone starts to stutter and is slower/less responsive even with overclocking (tried it up to 850Mhz) than with default settings! Now I have overclocked my N900 up to 750Mhz with the default settings (kernel-config limits 250 750) and it doesn't have this stutter effect but I cannot save energy with low energy profiles. Which setting in those profiles could cause this and how can I fix it? I tried to get this working but even after a reboot it doesn't do anything. What could be wrong? Thanks for help.
