CPUIDLE does not work on SMP Opteron system
Last modified: 2013-01-10 02:05:36 EST
Description of problem:
Cpuidle does not work on dual cpu quad-core Opteron system, sensors reports around 48C and 61C under 0 load for the first and second CPUs respectively. Both menu and ladder governors give similar results. Recompiling kernel with "CONFIG_CPU_IDLE is not set" gives around 35C and 41C under 0 load.
Version-Release number of selected component (if applicable):
All versions starting from original Fedora 9 kernel up to the latest kernel-18.104.22.168-108.fc9.x86_64.
Steps to Reproduce:
Additional info: It is probably stock kernel bug.
This should be fixed in the latest F9 test kernel, 22.214.171.124-29.fc9
126.96.36.199-29 is released. Is this bug fixed?
30+ days in state NEEDINFO, closing bug.
