Hi, just curious where CLK_USE_I586_CALIBRATION went ??
I used to use in my PPro, but not config (and LINT) tell me
it's no longer an option. With the I586_CALIBRATION the boot
message would correctly detect the CPU speed each and every
time. Now it's off by +/- 15%, and my clock has gained over
an hour in under a day.. :-(
What should I be using here?? I have the
CLK_USE_I8254_CALIBRATION option in the kernel right now. Maybe I
should have nothing "extra" in there?
TIA,
-Mark
