i've got the Problem after I did a fresh install of Fedora7 on my Fujitsu Siemens Amilo M3638G. It owns a 1.73GHz CPU but looking at dmesg, it gets being detected at 799Mhz. This is also stated at /proc/cpuinfo, But with the correct CPU-name string, but also at 799Mhz. When trying to use cpuspeed to change the frequency, it tells me that i'am running at MAX allready :-(
I had a look at /etc/sysconfig/cpuspeed and found out that the setting DRIVER is empty ( "DRIVER=" ) which means more or less that it should autodetect. I didn't found on the internet what setting for the driver would meet my centrino. But anyway i think since it gets not detected well during startup of the kernel , the driver setting for cpuspeed would be helpless.
EDIT: Maybe it's worth to mention, that under FC6 with kernel 2.6.19 and former versions it was working correct.
Does anyone have the same problems, or maybe a solution for this ?
A push in the right direction, to solve this problem would be very nice.
