*** Bug 495459 has been marked as a duplicate of this bug. *** From bug 495459, this is a new system, so its pretty likely not an issue of dust build-up or anything. Its an AMD laptop, so powernow-k8 is the cpufreq driver in question here. Have requested dmesg output after booting w/cpufreq.debug=7 to see if it reveals anything interesting. Here's a sizable excerpt from "dmesg", after booting with cpufreq.debug=7: __ratelimit: 84 callbacks suppressed cpufreq-core: target for CPU 0: 2000000 kHz, relation 1 powernow-k8: targ: cpu 0, 2000000 kHz, min 800000, max 2000000, relation 1 powernow-k8: targ: curr fid 0x0, vid 0x1e freq-table: request for target 2000000 kHz (relation: 1) for cpu 0 freq-table: target is 0 (2000000 kHz, 4876) powernow-k8: cpu 0 transition to index 0 powernow-k8: table matched fid 0xc, giving vid 0x13 powernow-k8: cpu 0, changing to fid 0xc, vid 0x13 cpufreq-core: notification 0 of frequency transition to 2000000 kHz cpufreq-core: notification 0 of frequency transition to 2000000 kHz __ratelimit: 172 callbacks suppressed cpufreq-core: target for CPU 0: 2000000 kHz, relation 1 powernow-k8: targ: cpu 0, 2000000 kHz, min 800000, max 2000000, relation 1 powernow-k8: targ: curr fid 0x0, vid 0x1e freq-table: request for target 2000000 kHz (relation: 1) for cpu 0 freq-table: target is 0 (2000000 kHz, 4876) powernow-k8: cpu 0 transition to index 0 powernow-k8: table matched fid 0xc, giving vid 0x13 powernow-k8: cpu 0, changing to fid 0xc, vid 0x13 cpufreq-core: notification 0 of frequency transition to 2000000 kHz cpufreq-core: notification 0 of frequency transition to 2000000 kHz __ratelimit: 92 callbacks suppressed cpufreq-core: target for CPU 0: 2000000 kHz, relation 1 powernow-k8: targ: cpu 0, 2000000 kHz, min 800000, max 2000000, relation 1 powernow-k8: targ: curr fid 0x0, vid 0x1e freq-table: request for target 2000000 kHz (relation: 1) for cpu 0 freq-table: target is 0 (2000000 kHz, 4876) powernow-k8: cpu 0 transition to index 0 powernow-k8: table matched fid 0xc, giving vid 0x13 powernow-k8: cpu 0, changing to fid 0xc, vid 0x13 cpufreq-core: notification 0 of frequency transition to 2000000 kHz cpufreq-core: notification 0 of frequency transition to 2000000 kHz Let me know if there's anything else you want me to try. As of this morning, with a fully-updated F11 beta system, the cooling fan oscillation problem isn't as bad as it was before, but it still happens. The fan will operate smoothly for a while, then kick into oscillation mode, then back to smooth, etc. So I'm still open to suggestions as to what I can test and report on. For unrelated reasons, I installed the koji kernel 2.6.29.1-106.fc11.x86_64 this morning and, since then, the cooling fan issue seems to have gone away and it's running smoothly (albeit pretty darned warm). Was there something specific that was fixed recently that dealt with this? In any event, things are looking good. If it goes to hell again, I'll let you know. This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
