From 67f8b470ec25ba24d6334061f4494330c847ac46 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 20 Sep 2017 15:19:33 -0700 Subject: [PATCH] Add 'ignore_resource_conflict' error It appears that some BIOSes reserve ACPI resources without using them, and acpi_enable_resources=lax seems to result in failures to load certain drivers. Introduce a 'ignore_resource_conflict' module parameter as alternate means to ignore ACPI resource conflicts.
