Revision ba4ba8a69dcb446450b5ddeca48a7bd15783f4c2 authored by Peter Oberparleiter on 27 July 2006, 12:00:23 UTC, committed by Martin Schwidefsky on 27 July 2006, 12:00:23 UTC
In special conditions where a subchannel rejects the HALT I/O-
instruction with a busy indication (cc 2), I/O may stall.
I/O request termination logic retries HALT I/O indefinitely
because it expects HALT I/O to alter the subchannel status which
is not true when cc 2 is returned.
In case of a busy indication, try CLEAR I/O instruction immediately.
