Re: Terrible interactivity with 2.6.0-t9-mm3
From: Prakash K. Cheemplavam

After sending out multiple patches I should have been more clear. Just
to avoid confusion:
* the init_cpu_khz patch goes along side Thomas' patch.
* the more experimental sched_clock() -> monotonic_clock() patch I just
sent out for testing replaces Thomas' patch.
I now tried the second one and it seems to work, tough I am not sure
whether the performance is as good as APCI timer deavt. It seems that
now CPU Hz is not shown anymore. Have a look at my dmesg:
