+Subject: [PATCH] mb/gigabyte/ga-g41m-es2l: Fix ACPI IRQ settings for SATA
+
+Previously, due to a bug in devicetree and incorrect IRQ
+settings in ACPI, SATA controller would not initialize
+any HDDs in the OS, even though it worked in SeaBIOS.
+The devicetree setting is not needed because SATA must
+function in "plain" mode on this board, as "combined" mode
+does not work at all.
