From 0430a8402ee6125c909ae3f4c3a89696e9a24077 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Mon, 4 Jun 2012 15:00:06 +0800 Subject: [PATCH 093/109] ACPI: Add a quirk for "AMILO PRO V2030" to ignore the timer overriding commit b939c2acf1dc42b08407ef5174f2e8d6f43dd5ea upstream. commit f6b54f083cc66cf9b11d2120d8df3c2ad4e0836d upstream. This is the 2nd part of fix for kernel bugzilla 40002: "IRQ 0 assigned to VGA" https://bugzilla.kernel.org/show_bug.cgi?id=40002 The root cause is the buggy FW, whose ACPI tables assign the GSI 16 to 2 irqs 0 and 16(VGA), and the VGA is the right owner of GSI 16. So add a quirk to ignore the irq0 overriding GSI 16 for the FUJITSU SIEMENS AMILO PRO V2030 platform will solve this issue.
