This morning, I checked the Exception Letters for our z9 and z10 processors. Both Exception Letters are dated May 28, 2008, and both still say that Segmentation Offload needs to be disabled.
I am not saying that IBM hasn't fixed the problem - I hope they have. But, the Exception Letters still say the problem is NOT fixed. FYI - the Exception Letters are found in ResourceLink by clicking on Fixes, and then Exception Letters.
