Bug Description
Binary package hint: linux-image-
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.

what is maybe more important: 2.6.22- 14-generic/ kernel/ arch/i386/ kernel/ cpu/cpufreq/ acpi-cpufreq. ko): No such device
sudo modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/
after that, in dmesg:
ACPI: Invalid _PSS data: freq is zero
sudo modprobe speedstep-centrino 2.6.22- 14-generic/ kernel/ arch/i386/ kernel/ cpu/cpufreq/ speedstep- centrino. ko): No such device
FATAL: Error inserting speedstep_centrino (/lib/modules/
nothing in dmesg after that.
all dmesg output in attachment
