cpu frequency scaling broken
Last modified: 2007-11-30 17:11:34 EST
Description of problem:
Version-Release number of selected component (if applicable):
Install the development version of the kernel
reboot the computer into new kernel.
Steps to Reproduce:
1. Install development kernel
2. Reboot into new kernel version
3. Notice errors related to cpu-frequency scaling
4. Notice cpu is at full speed.
CPU is pegged at full speed and does not scale.
Expected to have CPU scale according to workload.
I just upgraded from FC5 and noticed this problem after booting into the fully
updated Development condition.
The cpu frequency scaling is now fixed starting again at kernel 2.6.16-1.2252_FC6.
