From b042453f3892465e8372b95a0f42c0890df03445 Mon Sep 17 00:00:00 2001 From: Levente Kurusa Date: Tue, 22 Oct 2013 16:53:35 +0200 Subject: [PATCH] ACPI: Add Toshiba NB100 to Vista _OSI blacklist This patch adds Toshiba NB100 to the Vista _OSI blacklist. The _OSI(Windows 2006) method is bugged on the netbook resulting in messed up PCI IRQ Routing information. This was observed on a netbook whose SATA controller mode was set to Compatibility mode. The controller would then issue IRQs to IRQ#16 instead of IRQ#20, where it should have been. No side-effects were found during testing, everything is working as it did before.
