Thanks. I've resolved the program exception for which the SVC dump was taken and the SSIR entries are not related to the problem. However I am still puzzled that the SSIR entry does not identify the address of the SSAIR instruction it apparently represents.

So I am not sure what is missing here. Will the BSG entries help you resolve your issue?
