Hmm, it can't be the passive trip point, your BIOS doesn't declare one.
Only thing I could imagine is _PPC or some weird cpufreq bug.

Could you open a bug entry on bugzilla.kernel.org, put me into CC and
attach acpidump and dmesg output.

If you know how to compile the latest kernel, it would be great if you
could add CPU_FREQ_DEBUG=y and ACPI_DEBUG=y in the compile options and
boot with cpufreq.debug=7 and again post dmesg output after powernow-k8
got loaded and ondemand got activated for a short while.
