Same problem here. It was working with Dapper and after the Edgy upgrade it got broken. Fixed to the max. frequency of 1.73GHz.
That is what I get: $ cat /proc/cpuinfo | grep name model name : Intel(R) Pentium(R) M processor 1.73GHz $ sudo modprobe speedstep-centrino FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17-10-386/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device $ ls /sys/devices/system/cpu/cpu0/ crash_notes $ sudo cat /sys/devices/system/cpu/cpu0/crash_notes 1ff6c800 Would the workaround with 'p4-clockmod' work with Pentium M? -- speedstep-centrino module fails to load https://launchpad.net/bugs/66812 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
