commit ae96aefb5f26968c95a41f3be7e912448cd402fd Author: Denis 'GNUtoo' Carikli GNUtoo@no-log.org Date: Tue Feb 14 22:11:23 2012 +0100
M4A785T-M: fix TOM2. This commit is based on the commit 94fa3db36688e8db133aebe14d480b0c4722e4c9 (AMD Mahogany Fam10 ACPI table fixes.)
With commit permit to boot without pci=nocrs on the M4A785T-M board.
Before the fix dmesg contained the following: [ 0.452071] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) [ 0.480085] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) [ 0.788222] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359)
Now it only contains: [ 0.312102] TOM: 0000000080000000 aka 2048M
