The init_cpu_khz patch works as expected... THX! Well, but the sched_clock() -> monotonic_clock() patch seems to have a=20 problem... =46irst, everything works smoothly if the PIT or the TSC clock are selected= =2E (It=20 seems I cannot test the HPET timer due to missing hardware support) But when booting with the PMTMR clock selected, my Interactivity test fails= =20 again. :-( Maybe there is a problem in the PMTMR's monotonic clock part...?!
