CPU frequency gets stuck at the lowest frequency after resume from suspend
(ThinkPad T60p)
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.
Output of uname -a:
Linux walle
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
I had the same problem with mine, where it was pegged at 2800Mhz.
(current policy: frequency should be within 2.80 GHz and 2.80 GHz.)
Try the following: For each of your processor cores:
Core 0:
sudo cpufreq-set -c 0 -d 800Mhz -u 2800Mhz
Core 1:
sudo cpufreq-set -c 1 -d 800Mhz -u 2800Mhz
etc.,
I have this problem with just one out of four cores.

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
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
I don't know about T60p (yet, will keep an eye on it).
My issue is T43 - worked with intrepid, fails with jaunty. I already checked if
it could be temperature related, since that was my first suspect. But it didn't
look like that.
If it's temperature related what software is causing this, where
This should really be a high-priority bug. Running at 800 Mhz makes my
computer practically unusable for certain tasks, and forget multi-
tasking! It's extremely frustrating. I'm willing to help out with any
amount of debugging that I can provide, just let me know!

then turn off again. Trying to change the setting has no effect.

I am also experiencing this problem. It is becoming very annoying. Every

I'm still getting this problem.
I'm using the current pre-release of 8.10 (as of 25 Sept. 2008), with kernel
version:
Linux socrates 2.6.27-4-generic #1 SMP Wed Sep 24 01:30:51 UTC 2008 i686

My hardware is a Dell D830, with an Intel Core2 T9500 processor.
If I sleep the laptop,
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

I'm seeing the same behavior with the following setup. Processor speed
remains fixed at 1000MHz, and cpufreq-info says current policy:
frequency should be within 1000 MHz and 1000 MHz. even though 2000MHz
are possible and I'm using the performance governor. Other governors
give me the same result.

I can confirm the same behavior on the following Fedora 8 32bit system:

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