Same bug at me.

After suspending and resuming a laptop (Core Duo T2500, IBM T60), the clock speed of one CPU core goes up to maximum (2.0 GHz at me). The another core remains at low speed (certainly, no process consumes the CPU except minimal CPU usage of the usual ones like Xorg, etc.).

If I run

sudo powernowd

the clock speeds fall back to normal state (until next suspend/resume).

Release: Kubuntu 6.10, nothing special.
