Description Radek Liboska 2008-04-30 10:28:59 UTC
Description of problem:

CPU frequency scaling  (Intel(R) Core(TM)2 CPU) broken after upgrade from
kernel- to kernel-

Version-Release number of selected component (if applicable): #1 SMP Sat Apr 19 12:39:34 EDT 2008 i686 i686 i386 GNU/Linux

How reproducible:


Steps to Reproduce:
1.service cpuspeed status
cpuspeed is stopped
2.service cpuspeed start
3.service cpuspeed status
cpuspeed is stopped
Actual results:

cpuspeed service does not start, no cpufreq directory on

Expected results:

running cpuspeed service

Additional info: manual loading of modules has no effect as well

Comment 1 Radek Liboska 2008-04-30 10:53:00 UTC
- after the update to kernel- even the kernel-
lost its ability to run cpuspeed (with kernel-headers-

Comment 2 Dave Jones 2008-04-30 11:08:05 UTC
please boot with cpufreq.debug=7 and attach the output of dmesg.

dmseg says:

actually IS SpeedStep(TM) capable!

Comment 5 Dave Jones 2008-04-30 14:58:53 UTC
That 'not found' message is expected.  There are 3 different variants of
speedstep, and that message comes from the driver for the pentium-III era
version of speedstep.

Your CPU should be using acpi-cpufreq, but for some reason it looks like that
isn't getting loaded.

Can you try modprobe acpi-cpufreq from the command line, and see what that does ?

Also, the output of /proc/cpuinfo might be handy.

Comment 6 Radek Liboska 2008-04-30 15:14:51 UTC
$ modprobe acpi-cpufreq

Comment 7 Dave Jones 2008-04-30 15:24:13 UTC
ok, you have the est flag, so all should be good.  It looks like the BIOS for
some reason has broken P state tables.  Can you attach /proc/acpi/dsdt please ?

Also, you may want to make sure you're running the latest version of your BIOS
if there are updates available.

Comment 8 Radek Liboska 2008-04-30 16:02:42 UTC
I have encountered some problems with BIOS already (freezing, BIOS CRC checksum
error). I'll try re-flashing it.

Comment 10 Radek Liboska 2008-04-30 16:58:37 UTC
Dave, thanks for your help and sorry for wasting your time! The BIOS updating
solves the issue. Now the cpuspeed is working again. (However the
"speedstep-ich: Intel(R) SpeedStep(TM) capable processor not found" message is
still present)
You can close this bug.
Have a nice day and thanks again
