From 028cf917b258b11286437a1b96e64030f94fd46d Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Fri, 15 Dec 2006 17:18:14 +0100 Subject: [S390] Hipersocket multicast queue: make sure outbound handler is called A HiperSocket multicast queue works asynchronously. When sending buffers, the buffer state change from PRIMED to EMPTY may happen delayed. Reschedule the checking for changes in the outbound queue, if there are still PRIMED buffers.

The reason for this is, that before the reboot is done, the channel subsystem is shut down. During the reset on each possible subchannel a "store subchannel" is done. This operation can end in a program check interruption, if the specified subchannel set is not implemented by the hardware. During the reset, currently we do not have a program check handler, which leads to the described kernel bug. We install now a new program check handler for the reboot code to fix this problem.
