I think the calibration OF puts in the device-tree is crap or we are using the VIA to calibrate and we should not ... >From what I remember, Apple has additional calibration code in Darwin based on the KeyLargo timers (for machines with a KeyLargo). Might be worth implementing something similar. Look at pmac_calibrate_decr() in arch/powerpc/platform/powermac/time.c, and see wether it's calling via_calibrate_decr() or not on your machine. If not, try calling it and tell us if it improves calibration. Cheers, Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
