[S390] cio chpid offline.
After setting a path to a dasd offline at the SE, I/O hangs on that dasd for 5 minutes, then continues. I/O for which an interrupt will not be reported after the channel path has been disabled was not terminated by the common I/O layer, causing the dasd MIH to hit after 5 minutes. Be more aggressive in terminating I/O after setting a channel path offline. Also make sure to generate a fake irb if the device driver issues an I/O request after being notified of the killed I/O and clear residual information from the irb before trying to start the delayed verification.
