I believe this is a duplicate (excuse if anachronistic) of bug 183033, and is still present in later versions of the kernel If so, it is NOT simply cosmetic -- upon resume from suspend, cat /proc/cpuinfo | grep MHz indicates that one cpu is scaling while the other isn't.

Hi, On a clean install of Hardy Heron Alpha 5, upgraded to Alpha 6 with the newest kernel in the repository -- this problem still exists.

The Hardy Heron Alpha series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Note that we'll keep this report open against the actively developed kernel but this will be closed against 2.6.17.

I have the same exact problem, so it is confirmed. This is a kubuntu Edgy 6.10 install on a Toshiba A100-TA6. It has T2250 Centrino Duo. When the laptop is rebooted, both CPUs are running at 800MHz most of the time, and one or the other goes up to the full 1733MHz. This happens upon resuming from suspend, or from hibernate. The fan also goes fast and I can feel air coming out of the vents. It goes back to normal if I reboot the laptop. See this: $ grep MHz /proc/cpuinfo cpu MHz : 800.000 cpu MHz : 1733.000 The puzzling part is that both CPUs are in the same ACPI state regardless: $ diff /proc/acpi/processor/CPU? diff /proc/acpi/processor/CPU0/info /proc/acpi/processor/CPU1/info 1,2c1,2 processor id:0 acpi id: 0 --- processor id:1 acpi id: 1 diff /proc/acpi/processor/CPU0/power /proc/acpi/processor/CPU1/power 6c6 *C2: type[C2] promotion[--] demotion[C1] latency[001] usage[01822333] duration[007367703269] --- *C2: type[C2] promotion[--] demotion[C1] latency[001] usage[01743842] duration[007432976070] -- suspend/resume porblems with centrino duo https://launchpad.net/bugs/64070 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Were you able to manually reduce the speed of the second cpu? If so, how?

According to the forums post, you have to create a script in /etc/acpi/resume.d to restart powernowd (that sets your cpu power config to default, ondemand in both cores in my case). Further instructions in the link in my previous comment. If you want to manually change your cpu speed you can use cpufreq-selector. -- suspend/resume porblems with centrino duo https://launchpad.net/bugs/64070 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
