From 1278998f8ff6d66044ed00b581bbf14aacaba215 Mon Sep 17 00:00:00 2001 From: Myron Stowe Date: Wed, 26 Dec 2012 10:39:23 -0700 Subject: [PATCH] PCI: Work around Stratus ftServer broken PCIe hierarchy (fix DMI check) Commit 284f5f9 was intended to disable the "only_one_child()" optimization on Stratus ftServer systems, but its DMI check is wrong. It looks for DMI_SYS_VENDOR that contains "ftServer", when it should look for DMI_SYS_VENDOR containing "Stratus" and DMI_PRODUCT_NAME containing "ftServer". Tested on Stratus ftServer 6400.
