[PATCH] acpi: Add Toshiba NB100 to Vista _OSI blacklist
From: Levente Kurusa
Date: Tue Oct 22 2013 - 10:53:43 EST
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.
