Anton Piatek, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If so,
could you please test for this with the latest upstream kernel available (not

Had a similar problem with intel atom (2 cores, 1,6GHz) in ubuntu 12.04:
governor was ondemand, speed was always 800MHz (the lowest speed, and it felt
way more slow than "twice as slow")
Upgraded to 12.10, the problem persisted.
Installed package cpufreqd (which was not present), and then the s

Can you supply the ACPI dump when it gets stuck in a lower CPU frequency
state too? It does seem curious, but the "faster" CPU configuration
does not supply the _PSS in the tables, which is what was originally
limiting the CPU speed.

@Anton, I'm finding this one hard to understand, the ACPI tables in your
machine have the _PSS defined as:
Name (_PSS, Package (0x02)
{
Package (0x06)

0x02BC, // 700 MHz
0x7918,
0x000A,

Assuming I actually got the correct upstream kernel, it doesn't seem to

Let me know if there is another kernel you want me to try, or any other

I wonder if this is to do with a faulty BIOS frequency limit. To check
this out can you try the following:
Edit /etc/default/grub (you need to do this using root privilege) and
change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.ignore_ppc=1"
This seems to be an issue with the devfreq governors.
If you could also please test the latest upstream kernel available that would
be great. It will allow additional upstream developers to examine the issue.
