Bug Description

Binary package hint: linux-image-2.6.22-14-generic

For many releases Ubuntu has been one of the few distributions to ship a patched kernel for my laptop cpu:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.70GHz
stepping : 6
cpu MHz : 1700.000
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe up est tm2
bogomips : 1191.56
clflush size : 64

This cpu requires the Dothan patchset to correct the cpu scaling tables.

It was working fine with Fiesty but when I upgraded to Gusty the speedstep_centrino module refused to load stating "device not found". So I tried a clean install of Gusty (Kubuntu) RC but the problem insued. I also then installed Fiesty and upgraded my system and retained the old kernel, when I boot into the fiesty kernel on my updated gusty install speedstep_centrino loads properly.

Please let me know if there is any other information I can provide!

Same here: frequency scaling not working, neither by acpi-cpufreq nor speedstep-centrino.
Notebook Maxdata 8100X (PentiumM 1.6GHz) ICH4

cat /proc/cpuinfo

what is maybe more important:
sudo modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.22-14-generic/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

after that, in dmesg:
ACPI: Invalid _PSS data: freq is zero

sudo modprobe speedstep-centrino
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.22-14-generic/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

nothing in dmesg after that.

all dmesg output in attachment

after some search, it seems that it is the same as

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/93331

or:

http://bugzilla.kernel.org/show_bug.cgi?id=8228

so please, patch dapper kernel with tables for Dothan processor - kernel.org seems to ignore the problem (problem is solved by bios upgrade). For my laptop there is no BIOS upgrade, and it does not have option in it to enable frequency scaling

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
