SDK 2.2 profiler timings problem

Is anyone else getting inconsistent kernel times with SDK 2.2?

I was getting some pretty varied results (up to ~40% swing) in my kernel timings with SDK 2.2/10.7b.

I do not get this problem with SDK 2.1/10.5.

Is this a known bug?

For example, for the DCT sample with SDK 2.2 I get a swing from ~6.6 to ~10.xx but with SDK 2.1 it's a consistent ~6.6 and for the Twister sample I get a swing from ~14.xxx to ~18.xx with SDK 2.2 but with SDK 2.1 its a consistent ~9.3xxx....

And I mean like with SDK 2.1, the timings are pretty much rock solid but with SDK 2.2 they are all over the place in those ranges.
