--- Comment #3 from Thomas Renninger <tr...@suse.de>  2010-11-06 20:04:54 ---
This should be an ACPI, not a cpufreq bug.
Some things you could check:
  - BIOS up-to-date?
  - Is the limitation done through _PPC:
cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit


The bios limit (_PPC) was not evaluated at (processor.ko) driver load time, but
only when CPU notification events where thrown. It sounds like you see this.
This got fixed by commit:
455c0d71d46e86b0b7ff2c9dcfc19bc162302ee9

Above patch could make trouble on other systems and you set "Fedora tree".
Can you double check that above commit is included in your tested kernel.
