Most recent kernel where this bug did not occur: 2.6.22.6 Distribution: Debian GNU/Linux unstable Hardware Environment: Thinkpad R52, Pentium M Dothan 750 Problem Description: # modprobe speedstep_centrino FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.23.1/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device speedstep_centrino can't find a device any more. Earlier kernel versions worked without problems. CONFIG_ACPI=y CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y CONFIG_CPU_FREQ_STAT=y CONFIG_X86_SPEEDSTEP_CENTRINO=m CONFIG_X86_SPEEDSTEP_CENTRINO_TABLE=y
I tried acpi_cpufreq and it works without problems. But I'm curious why speedstep_centrino doesn't work anymore.
Hi. What's up? Any plans to fix this problem? Or will this module become obsolete? Some responses would be really nice. Regards, Alex
There is a plan to use acpi-cpufreq, so it's a good news. As for breakage of speedstep-centrino, maybe you can enable ACPI_DEBUG and provide dmesg and /var/log/messages while inserting the module. Have you tried latest kernel by chance?
There are no messages while inserting speedstep-centrino. CONFIG_ACPI_DEBUG, CONFIG_CPU_FREQ_DEBUG, CONFIG_DEBUG_KERNEL and CONFIG_DEBUG_BUGVERBOSE enabled. Same problem with kernel 2.6.23.12.
speedstep-centrino is deprecated, you have to use acpi-cpufreq. According to comment #1: > I tried acpi_cpufreq and it works without problems. But I'm curious why > speedstep_centrino doesn't work anymore. IMO this one can be closed -> doing so.
