Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All z/VM users * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** ABENDFRE016 occurs after a device encounters a reset CRW. While a guest IORBK was still queued for execution on the RDEV its storage was released by the virtual interrupt handler while it was purging the VDEVPIOR (pending interrupt) queue as part of the reset CRW occurrence. The purge of the VDEVPIOR queue was in error in that IORBKs on that queue were being located via the IORFPNT pointer when they should have been located using the IORPIOR pointer. After the guest IORBK gets executed and processed through the virtual interrupt handler its storage is released again resulting in an ABENDFRE016.
Problem conclusion
ABENDFRE016 - Processing of the VDEVPIOR queue for reset CRW processing was modified to correctly use the IORPIOR pointer when locating IORBKs on the queue instead of the IORFPNT.
