QDIO returned from EQBS instruction in any case after return code CCQ=96 was issued regardless whether buffer states for at least one buffer were extracted or not. This caused FCP devices to hang when running under z/VM and having QIOASSASIST=ON and having high I/O rates. In order to fix this qdio return code processing of EQBS instruction after CCQ=96 is changed that buffers are returned and if no buffers where extracted the instruction is repeated at once.
