I had some timing problems also but Andrew pointed out the following:

Seems that this is because different parts of the kernel are using
different values of HZ (!).

In include/asm-i386/param.h, please add:

#ifdef __KERNEL__

+#include <linux/config.h>

#ifdef CONFIG_1000HZ

Here is a patch for that change:
