From 14d1399f0c5a075570df047aaebe592a59e5e293 Mon Sep 17 00:00:00 2001 From: Drew Moseley Date: Sat, 5 Jul 2014 17:10:52 -0400 Subject: [PATCH 05/13] ACPI: Set acpi_enforce_resources to ENFORCE_RESOURCES_LAX On some AMD platforms, the SMBus IO region 0xb00 - 0xb07 conflicts with the corresponding ACPI SystemIO region. This prevents the SMBus host controller driver to function correctly. We set acpi_enforce_resources to ENFORCE_RESOURCES_LAX so that the SMBus driver can work normally, even though a warning message notifying the conflict is printed in system logs.
