Hi, Carsten,
Thanks for the offer to help, but the fix was Kris Buelens' comment that a
DCSS must start and end on megabyte boundaries. That means the "end page"
value should end in x'FF', or at least the subsequent DCSS needs to have a
"start page" value ending in x'00' to avoid overlaps. That fact should
probably explicitly be called out in the XIP documentation. (In a blatant
attempt to deflect blame for my shallow z/VM skills. :)
