What are the proper cpufreq drivers? processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 3 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 4 cpu MHz : 3000.000 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe constant_tsc pebs bts pni dtes64 monitor ds_cpl cid xtpr bogomips : 5984.09 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 32 bits virtual power management: From what I gather in the bug, p4-clockmod is the proper module to load, but that ondemand is not compatible with it. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane [email protected] Boulder, CO 80301 http://www.cora.nwra.com _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
