From 2265e98b72df477a38271787485e2cd33df212b4 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Sun, 17 Feb 2019 12:37:17 +0100 Subject: [PATCH] lsi: check if SIGP bit is already set in Wait reselect If SIGP is set, the 'Wait for Reselection' command should jump immediately to the address stored in the second DWORD of the instruction. This fixes spurious hangs in the HP-UX 11.11 installer when the SIGP bit gets set by the kernel before the 'Wait for Reselection' command is executed by SCRIPTS.
