dmesg output with cpufreq.debug=7
Description drago01 2008-03-21 09:19:02 UTC
The patch "linux-2.6-acpi-fix-sizeof.patch" breaks acpi-cpufreq on my laptop. It has been backported to fedoras 2.6.24 kernels (now removed again due to this bug). I was asked to report it here. See: https://bugzilla.redhat.com/show_bug.cgi?id=436959#c17 (starting from this comment). I will attach some debug infos after submitting this.

By break acpi-cpufreq I mean it fails to load with "no such device" and the cpu stays at max clock. I hope the infos provided are enough if not feel free to ask for more.

The offending patch from bug 9558 was not included upstream. Unclear why it was included in fedora before it hit upstream or even the -mm tree, maybe that was a mistake. So this isn't an upstream regression, but rather it is feedback on the patch proposed for bug 9558. Closing as a duplicate of bug 9558. *** This bug has been marked as a duplicate of bug 9558 ***
