This is also found on a Dell D800 laptop running Ubuntu Server 9.10. Frequency is always stuck on the lowest (600 MHz). The only way to disable it is to boot with acpi=off, but that induces other problems, most notably the 'sensors' command no longer works.

[Bug 138465] Re: CPU frequency gets stuck at the lowest frequency after resume from suspend (ThinkPad T60p)
Update on my sitation: I've removed the system fans and replaced them with oversized passive heatsinks. When the bios doesn't detect the system fans, it disables SpeedStep and locks the CPU frequency at its lowest value. Re-connecting the fans does not help unless the computer is turned off and a full POST (not the quick-POST) is performed. In short, this is a hardware/bios problem, not a Linux bug.

Follow on from atany: I also have a Dell M1330 running Jaunty. In addition to atany's findings, I have found that after a suspend/resume or removal of AC power, I can change the frequencies if the power is disconnected. On reconnecting AC power the frequencies revert to 800MHz and I am unable to change them. See attached transcript of testing (sorry it's a bit long but it is annotated).

[Bug 138465] Re: CPU frequency gets stuck at the lowest frequency after resume from suspend (ThinkPad T60p)
I can confirm this bug on Dell XPS M1330 using Jaunty upgraded from Intrepid
(which was working perfectly).
This happens to me not only after suspend/resume but also after I disconnect AC
power and then reconnect it. Frequency is then locked at 800MHz with no related
messages in logs.
As it was already pointed out, directly writing max value to
cpu{0,1}/cpufreq/scaling_max_freq has no effect.

I've been running Jaunty on my T60p for sometime now and it seems to be a non issue. Also be sure you keep the fan running or the CPU cool. I know if you authorize the CPU Frequency Scaling Monitor 2.26.1 you can maunally set the CPU speed or policy and it works well. Grag a copy of tpfan-admin (thinkwiki) and run it at 100% if you think the CPU's hot. Let me know your findings. I think it's a heat related issue, not suspend, not on Jaunty at least.

As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.

Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel.

[Bug 138465] Re: CPU frequency gets stuck at the lowest frequency after resume from suspend (ThinkPad T60p)
On a thinkpad, the only way I found out how to have proper suspend/resume working is by to have this: In file /etc/acpi/suspend.d/10-thinkpad-standby-led.sh append this line at the end: /etc/init.d/powernowd stop In file /etc/acpi/resume.d/90-thinkpad-unstandby-led.sh append this line at the end: /etc/init.d/powernowd start Perhaps this is relevant to you, since powernowd controls the frequency of the CPU. -- CPU frequency gets stuck at the lowest frequency after resume from suspend (ThinkPad T60p) https://bugs.launchpad.net/bugs/138465 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Nope... the previous workaround does not worked. It scaled once, but after next sleep/resume cycle it got stuck at 1Gz again...

Below is the output from cpufreq-info, as you can see it says [I]frequency should be within 1000 MHz and 1000 MHz[/I].

CPU scales up and the output above says should be withtin 1000 MHz and 2 GHz. I have been trying to fix it myself. For instance I added the following to /etc/default/acpi-support (trying to reload CPU scaling kernel modules on suspend/resume): [CODE]MODULES=cpufreq_stats cpufreq_conservative acpi-cpufreq[/CODE] It did not help. Then I tried [CODE]sudo cpufreq-set -u 200 or sudo cpufreq-set -u 2GHz[/CODE] Those did not do anything either - CPU still could not get up to 2Gz. Also I wet to /sys/devices/system/cpu and run these commands as root: [CODE]echo 200 cpu0/cpufreq/scaling_max_freq echo 200 cpu1/cpufreq/scaling_max_freq [/CODE] ... and nothing happens. Those two files still say 100. Normally (after reboot) they report 200 and I can write other values into them. At this point I am not sure what else can I try. Obviously I should update wakeup/resume scripts with some commands to bitch-slap cpu frequency scaling module, but I cannot figure out what to do. Here is my /etc/default/cpufrequtils [CODE]ENABLE=true GOVERNOR=conservative MIN_SPEED=100 MAX_SPEED=200 [/CODE] Here is my /etc/modules [CODE]lp cpufreq_stats cpufreq_ondemand cpufreq_conservative cpufreq_powersave acpi-cpufreq # this is what Core 2 Duo needs. fuse [/CODE] This is very frustrating.
