I guess there is trouble with the kernel module (which is actually part of the monolithic kernel for Fedora anyway) that does cpuspeed for your brand of CPU. cat /var/log/messages | grep power or dmesg | grep power I get something like this: # dmesg | grep power powernow-k8: Found 2 AMD Athlon 64 / Opteron processors (version 1.60.0) powernow-k8: 0 : fid 0xe (2200 MHz), vid 0xa (1300 mV) powernow-k8: 1 : fid 0xc (2000 MHz), vid 0xa (1300 mV) powernow-k8: 2 : fid 0xa (1800 MHz), vid 0xc (1250 mV) powernow-k8: 3 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV) indicating powernow-k8, the module that does the cpuspeed dirty work, is happy. The lack of the /sys entry may suggest the module was unhappy in your case at boot time, it which case you might find a complaint instead. -Andy -------------- next part -------------- A non-text attachment was scrubbed...
