Public bug reported: "acpi_cpufreq" should be built always as module and NEVER builtin because it prevent phc-linux being loaded, and also any other acpi_cpufreq replacement provided by the vendor if any.
"phc-linux" is very important if you need to downvolt some cpu. It's important, especially for some ThinkPad notebook like the Edge 15 0301-J4G that hang frequently over 100C because of buggy voltage regulation, even new, clean fan, etc... Since I can't see any problem building it as a module and it should not cause any regression it should be made even on 14.04 LTS, and for any future release. You can read about linux-phc here: http://www.linux-phc.org/forum Also having linux-phc in the default kernel would be great but it may need some work. Not asking to fix in the mainstream kernel somethink so specific and hardware bug related, but please please please don't force anyone has this problem to rebuild a custom kernel because it's very annoying, just build acpi_cpufreq as module and not builtin. -CONFIG_X86_ACPI_CPUFREQ=y +CONFIG_X86_ACPI_CPUFREQ=m Ubuntu is the only distro I use that has ACPI_CPUFREQ=y, should I move to Fedora or any other but Ubuntu? Also Debian has ACPI_CPUFREQ=m. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1472968 Title: acpi-cpufreq should be built as module and not built-in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1472968/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
