I was able to solve my broken ACPI tables by decompiling and fixing the DSDT.
The frequency field for the 600 MHz state was 0, hence the line in dmesg: "ACPI: Invalid _PSS data: freq is zero" I set it to 600, compiled it again and added it to the initrd. Now I can use acpi-cpufreq to scale the cpu clock to either 600 or 1600 MHz (not the full range, but that's enough). It even works in Vista with the DSDT registry override. Keep the good work with Ubuntu! 2008/2/13, Colin King <[EMAIL PROTECTED]>: > > ** Changed in: linux (Ubuntu) > Assignee: Ubuntu Kernel Team (ubuntu-kernel-team) => Colin King > (colin-king) > > -- > [GUTSY] cpu freq scaling not working anymore > https://bugs.launchpad.net/bugs/132271 > You received this bug notification because you are a direct subscriber > of the bug. > -- [GUTSY] cpu freq scaling not working anymore https://bugs.launchpad.net/bugs/132271 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
