From d8dd0641c06d39b87970650d7f9a0c8c8c395511 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Tue, 28 Feb 2012 15:31:35 -0600 Subject: [PATCH] x86/PCI: do not tie MSI MS-7253 use_crs quirk to BIOS version BugLink: http://bugs.launchpad.net/bugs/981162 commit a97f4f5e524bcd09a85ef0b8821a14d35e69335f upstream. Carlos was getting WARNING: at drivers/pci/pci.c:118 pci_ioremap_bar+0x24/0x52() when probing his sound card, and sound did not work. After adding pci=use_crs to the kernel command line, no more trouble. Ok, we can add a quirk. dmidecode output reveals that this is an MSI MS-7253, for which we already have a quirk, but the short-sighted author tied the quirk to a single BIOS version, making it not kick in on Carlos's machine with BIOS V1.2. If a later BIOS update makes it no longer necessary to look at the _CRS info it will still be harmless, so let's stop trying to guess which versions have and don't have accurate _CRS tables.
