Did this problem exist on the earlier kernel?

This value is way too small than normal. It means that either the clocking or the calculation of the position in intel8x0_measure_ac97_clock() is wrong. Could you check what is the value if ichdev->position in that function?

Usually it's a bit slower than that. See Documentation/sound/alsa/ALSA-Configuration.txt.
