At the moment, this is the only one I know of. The number of test failures on Power is getting relatively short. There are about 15ish tests that are currently failing on Power 10. I have the list and have been adding notes for each test as to what the issue is or is fixed by a patch under development. I have a couple of patches that have been posted and approved and a couple that I am working on still. Let me refresh the list and my notes and I can send it out so you can see where we are at with the regression test clean up. Carl
