Re: [arch-general] cpufreq stopped working

When I said that the problem also happened with kernel 3.3.8, I was wrong (because that time I forgot modprobing acpi_cpufreq). So, I just tested different kernel versions and this started happening with 3.4.0; it works fine until 3.3.8. And the problem is present in both vanila en -ck versions. I think that booting from LiveCD isn't necessary since the bug seems pretty clear, or so you think that I should also test another distribution with linux 3.4? I don't think that there are already LiveCD's available with such a recent kernel. Yes, you are right. If 3.3.8 was fine you don't have to test other kernel versions...

Some details of my box: x86_64, SSD linux-ck-corex 3.4.4-2, but the same happens with linux 3.4.4-2. I also tested linux-3.3.8-1 without luck nvidia-ck-corex 302.17-1 systemd, but the same happens when booting with standard initscripts I have only ArchLinux installed in my laptop since I bought it (so I cannot test in Window$ if frequency scaling is working) I found a similar report 2 months ago, apparently not solved yet: https://bbs.archlinux.org/viewtopic.php?id=140259 I don't have overheating problems though. CPU runs at about 40 °C all the time. Here is another similar problem, but also without a solution: https://bbs.archlinux.org/viewtopic.php?id=142237 I don't really know what else to do. I would really appreciate some help with this. Thanks for reading. -- Martin Código de novios Falabella: 585855-00 (gracias!) No envíen archivos pesados por mail.
