I can confirm that with the -19 kernel from hardy-proposed it works

Moreover, the kernel does not issue any warnings or error messages
whatsoever during a suspend/resume cycle. I believe that with earlier
kernels there were usually some cryptic ACPI errors.

I'm no kernel hacker, but that does look very interesting... in fact,
the lines before and after look related as well:
[0.574636] ACPI Error (psloop-0136): Found unknown opcode 17 at AML address
c28b27c3 offset 0, ignoring [20070126]
[0.574645] ACPI Error (psargs-0355): [DBþÿ]
Same problem as in description happens to me, with the following system:
Ubuntu 7.10
Kernel: Linux moria 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686
GNU/Linux
Dell Latitude D630 Laptop
Processor: Intel Core 2 Duo T7300 (2x 2 GHz)
Before suspend, frequency scaling is working
** Attachment added: 'cpufreq-info' directly after reboot, before suspending

To clarify, I'm talking about Suspend-to-RAM.
** Attachment added: 'cpufreq-info' after resuming from suspend
http://launchpadlibrarian.net/12134859/cpufreq-info-after-suspend.log
** Changed in: linux-source-2.6.22 (Ubuntu)
Sourcepackagename: None = linux-source-2.6.22
Status: New =
Tested with LiveCD of new Hardy Alpha 5:
CPU1 now stays at 2 GHz after resume from suspend. (Same behaviour as
with older Gutsy Kernels)

The attached dmesg is from booting normally, working for a while, then
suspending and resuming. The suspend begins at timestamp 5712. In
particular, the line
[0.574649] ACPI Error (psparse-0537): Method parse/execution failed
[\_PR_.CPU1._PCT] (Node 81007c3efb60), AE_NOT_FOUND

Try this:
--code--
modprobe -r acpi_cpufreq
modprobe acpi_cpufreq
--/code--
This restored the symlink to CPU0's cpufreq dir for me. I've modified
the acpi-scripts directory in etc (/etc/acpi/resume, specifically) to do
this now, and everything's fine. I've added those lines to
For completeness, output from sudo lspci -vvnn :

As for unloading acpi-cpufreq, that doesn't work for me since it's
marked in use by the kernel.
