Package: base
Severity: normal
I don't exactly know wether this bug related to base system or to linux kernel
or
cpufreq subsystem
I'm using cpufreq for dynamic CPU scaling on my notebook Dell D630.
After resuming from suspend2ram cpu scaling is lost for core #1.
Below is the cpufreq-info output before and after suspend2ram:

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 2.20 GHz
available frequency steps: 2.20 GHz, 2.20 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: userspace, powersave, ondemand, conservative,
performance
current policy: frequency should be within 800 MHz and 2.20 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 2.20 GHz

no or unknown cpufreq driver is active on this CPU
--------------------------------
manual reloading acpi_cpufreq kernel module helps to turn CPU 1 scaling on.
