Given what you explained in the previous patch version and the desire to correlate with other system wide activity, that might make more sense. Looking at the kernel's log for debugging performance or utilization or just to get a glimpse of what is going on is not quite suited past probe.
The debug prints have served our purpose up to this point.
But, in the interest of getting the other driver patches accepted I will drop this patch from the series and we will investigate further.

Thanks,
 Scott
