Are you still having this issue with the 3.4 or 3.5 kernel updates? Still the same on 3.4.9 # Mass update to all open bugs. Kernel 3.6.2-1.fc16 has just been pushed to updates. This update is a significant rebase from the previous version. Please retest with this kernel, and let us know if your problem has been fixed. In the event that you have upgraded to a newer release and the bug you reported is still present, please change the version field to the newest release you have encountered the issue with. Before doing so, please ensure you are testing the latest kernel update in that release and attach any new and relevant information you may have gathered. If you are not the original bug reporter and you still experience this bug, please file a new report, as it is possible that you may be seeing a different problem. (Please don't clone this bug, a fresh bug referencing this bug in the comment is sufficient). With no response, we are closing this bug under the assumption that it is no longer an issue. If you still experience this bug, please feel free to reopen the bug report. |
Description of problem: We have an Intel DP55WB motherboard with an Intel i7 860 CPU (quad core, 2.8GHz). Although turboboost and speedstep are enabled in the BIOS, the processor never switches into the turboboost state, when running a single core processor-intensive job. The BIOS is configured to turboboost at 3.5 GHz (no non-standard overclocking) for a single core job. Hyperthreading is disabled. The Cstate support is switched on, too. The latest BIOS for this motherboard is installed (WBIBX10J.86A). We have another system with the same CPU and a Gigabyte P55-UD3 motherboard. The turboboost works in this system. When booting, cpupower reports: [ 16.290367] cpupower[845]: Setting cpu: 0 [ 16.290476] cpupower[845]: Error setting new values. Common errors: [ 16.290605] cpupower[845]: - Do you have proper administration rights? (super-user?) [ 16.290785] cpupower[845]: - Is the governor you requested available and modprobed? [ 16.290991] cpupower[845]: - Trying to set an invalid policy? [ 16.291133] cpupower[845]: - Trying to set a specific frequency, but userspace governor is not available, [ 16.291313] cpupower[845]: for example because of hardware which cannot be set to a specific frequency [ 16.291499] cpupower[845]: or because the userspace governor isn't loaded? The turbostat program reports the following with a single-core mprime process: core CPU %c0 GHz TSC %c1 %c3 %c6 %pc3 %pc6 27.11 2.80 2.80 1.41 3.94 67.55 0.00 0.00 0 0 2.04 2.80 2.80 2.52 5.46 89.98 0.00 0.00 1 1 2.35 2.80 2.80 1.32 2.26 94.07 0.00 0.00 2 2 4.03 2.80 2.80 1.79 8.04 86.14 0.00 0.00 3 3 100.00 2.80 2.80 0.00 0.00 0.00 0.00 0.00 Version-Release number of selected component (if applicable): 3.3.0-8.fc16.x86_64 How reproducible: Every time Steps to Reproduce: 1.
