From cfca8634132c1b2f89c39f681ae2aa1fe227c9f5 Mon Sep 17 00:00:00 2001 From: Feng Tang <feng.tang@intel.com> Date: Mon, 4 Jun 2012 11:06:35 +0800 Subject: [PATCH 3/3] ACPI: Add a quirk for "AMILO PRO V2030" to ignore the timer overriding
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.
