When the SIE exited by a DAT access exceptions which we can not resolve, the guest tried to access a page which is out of bounds and can not be paged-in. In this case we have to signal the bad access by injecting an address exception. However, address exceptions are either suppressing or terminating, i.e. the PSW has to point to the next instruction when the exception is delivered. Since the originating DAT access exception is nullifying, the PSW still points to the offending instruction instead, so we've got to forward the PSW to the next instruction. Having fixed this issue, we can now also enable the TPROT interpretation facility again which had been disabled because of this problem.
