[Bug 355232] Re: acpi-cpufreq/powernow-k8 should not be built-in into the kernel image
I have a Raon Digital Everun Note UMPC and I need to replace the not working powernow-k8 code with a code that at least makes the conservative governor work. Currently the Turion X2 TL-56 is always running at 1200 MHz instead of 800 MHz. This results in 70 minutes battery life instead of 115 mins. I'm seriously considering to change to another distribution. The code that is at least partially working (ondemand and userspace crash the system) can be found here. http://www.schugy.de/Linux/Raon%20Everun%20Note/powernow-k8-src.zip Thanks for any support! -- acpi-cpufreq/powernow-k8 should not be built-in into the kernel image https://bugs.launchpad.net/bugs/355232 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am in the same boat as most ppl above. I have been using ubuntu since breezy and undervolting the AMD Turion on my laptop since feisty. Usually I check to make sure the usual suspects (X, suspend/hibernate) have no issues before upgrading but did not think something basic as acpi/powernow would be changed! Undervolting saves battery life, cpu temperature and my hands (from CTS).

[Bug 355232] Re: acpi-cpufreq/powernow-k8 should not be built-in into the kernel image
I have a Raon Digital Everun Note UMPC and I need to replace the not working powernow-k8 code with a code that at least makes the conservative governor work. Currently the Turion X2 TL-56 is always running at 1200 MHz instead of 800 MHz. This results in 70 minutes battery life instead of 115 mins. I'm seriously considering to change to another distribution. The code that is at least partially working (ondemand and userspace crash the system) can be found here. http://www.schugy.de/Linux/Raon%20Everun%20Note/powernow-k8-src.zip Thanks for any support! -- acpi-cpufreq/powernow-k8 should not be built-in into the kernel image https://bugs.launchpad.net/bugs/355232 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

+1 from another AMD Turion and PHC user trying to reduce CPU temperature (50C -> 30C) and extend battery life. I would really like to keep using Ubuntu, but compiling a custom kernel to enable undervolting is very time-consuming and could convince me to switch to another distro.

I am in the same boat as most ppl above. I have been using ubuntu since breezy and undervolting the AMD Turion on my laptop since feisty. Usually I check to make sure the usual suspects (X, suspend/hibernate) have no issues before upgrading but did not think something basic as acpi/powernow would be changed! Undervolting saves battery life, cpu temperature and my hands (from CTS).
