That should probably read: 16 bit counters are not accurate enough to be used. Right? > Do no allow them to be probed by tested max counter value. I really do not understand why you want to do this. Accuracy is not really a reason to dismiss working hardware right away. What you can do is to lower the rating so other eventually available hardware will be preferred. I might be missing something, but if so this is obviously missing in the changelog. Thanks, tglx
