OK, thanks! I'm assuming that the topmost two sets of data are for the "without the patch" case whereas the other three correspond to the "with the patch" case. If so, the processor clearly enters PC10 in both cases and the residency percentages are similar. The numbers of times the POLL state was selected in the first test look kind of unusual (relatively very large), but other than this the patch doesn't seem to make much of a difference, so I'm not going to apply it. Thanks!
