Public bug reported: Well, subject says it all. I never got anything except 800Mhz on my laptop after installing Karmic (previously it worked fine under Debian with 2.6.30-somerc-built-kernel).
Here is contents of /sys/devices/system/cpu/cpu0/cpufreq: == affected_cpus == 0 == cpuinfo_cur_freq == 800000 == cpuinfo_max_freq == 2401000 == cpuinfo_min_freq == 800000 == cpuinfo_transition_latency == 10000 == ondemand == cat: ondemand: Is a directory == related_cpus == 0 1 == scaling_available_frequencies == 2401000 2400000 1600000 800000 == scaling_available_governors == conservative ondemand userspace powersave performance == scaling_cur_freq == 800000 == scaling_driver == acpi-cpufreq == scaling_governor == ondemand == scaling_max_freq == 800000 == scaling_min_freq == 800000 == scaling_setspeed == <unsupported> == stats == cat: stats: Is a directory Note the scaling_max_freq. Unlike #138465 it happens every time, not only after suspend/resume.
