I have ran C&Q for years on dozens of machines without any problems. Although I disable powernowd and just use the in kernel frequency adjustment with ondemand and set the up threshold low. This is what I have in a startup file: echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo 15 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold Which means if the CPU goes over 15% cpu usage it bumps up to the next level.
