Thanks Don.
I suspect I have ASID 4 in my dump since I can set the ASID of the abending 
address space and I can issue the SYSTRACE ALL (and other flavors) and I get 
results formatted.

I'll poke around in ASID 4 and see what I can glean.

The trace buffers are actually in the TRACE address space (ASID 4),
so you'd need to capture that along with your program address space.
I've never seen any control blocks for that stuff though.
