Yes, sorry, I forgot:
# dmidecode -s bios-version && dmidecode -s bios-release-date
Version 1.80
04/18/2013
The issue has changed but not by the BIOS upgrade, but by the procedure I
mention in the blog post. Basically changing:
PowerManagement
-> BIOS Power Management
-> Battery Save Mode (using custom settings)
-> Processor Speed
<Low>
To <High>
With that change, the ondemand governor works fine, I don't remember if any of
the current extra options I pass to the kernel currently are needed or if I
added them to deal with other problems. The current set of extra options I'm
using are:
acpi_osi=Linux acpi_backlight=vendor pcie_aspm=force i915.i915_enable_rc6=7
i915.i915_enable_fbc=1 i915.lvds_downclock=1
With this configuration, the only remaining issue I get is I can't
control the brightness after a suspend-resume with the keyboard keys (I
have to manually write to
/sys/class/backlight/intel_backlight/brightness). I think if I changed
the parameters above in some way, the brightness problem was gone but
the cpufreq issues came back. But I might be remembering incorrectly,
last time I experimented with this was a LONG time ago.

Title:
[Toshiba Satellite -10J] cpufreq is not working properly
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I'm trying Ubuntu 12.04 beta2 and I'm having a problem with cpufreq.
The default governor is ondemand and it's not working properly, the
frequency is stuck at the lowest one, which makes the notebook really
annoying to use. I've tried the performance governor and it looks like
the CPU goes to the maximum frequency, but when querying with cpufreq-
info, I still see the minimum freq, but in the statistics about the
frequencies used, I see the maximum frequency getting more and more
percentage of use.
Finally I tried the convervative governor, and it really look like it
behaves like the ondeman should. The frequency is rapidily increased
as needed and dropped down again when is not needed anymore. This is
the only governor that seems to be changing the frequency in a way
cpufreq-info can really see it, as I see the frequency going up and
down when using that governor. The userspace governor also seems to be
working as expected.
Another strange this is that among the supported frequencies, I get
1.60GHz (the maximum frequency supported) listed twice.
Here is an example run of cpufreq-info:

My notebook is a Toshiba Z830, I guess all the proper information has
been submitted to the bug already, otherwise please let me know what
other information do you need. It would be nice if the final Precise
release goes out without this issue, as it really will get people a
very bad impression about Ubuntu because their notebooks will seem to
be too slow!
Thanks.
