Product: Power Management Version: 2.5 Kernel Version: 2.6.30+ Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq AssignedTo: cpufreq@vger.kernel.org ReportedBy: v_2e@ukr.net Regression: Yes Hello! I use a laptop with Mobile AMD Sempron processor and I've been experiencing the following problem since kernel version 2.6.30: When I work from AC power adapter, everything is fine - the whole set of frequencies for my processor are avalable (namely, 800 MHz, 1600MHz, 1800MHz, 2000MHz and 2200MHz). When I unplug the AC adapter, the CPU switches to 800MHz mode and I cannot make it use any of the higher frequencies. I know for sure that this worked fine with kernel v.2.6.29. This is very inconvenient - to use the lowest available frequency every time I work from the battery. I have reported this bug to Gentoo Bugzilla at first. Here is the link: http://bugs.gentoo.org/show_bug.cgi?id=328395 There are some details on this story on that page. I hope the bug (if it is one) will be fixed soon. Thanks.
