I've tried 2.4 and 2.5 kernels, and I get the same results. From my reading of the code, it should tick once a second. However, I have had the time between ticks vary from around 33 to over 100 seconds. Tbe time between ticks is different on every boot, but is consistent once booted. Is there some divider register that's not getting initialized?
