From 35a7c64fbc77bab4ca8ae477e8ab278ccd679ce2 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Mon, 22 Jun 2009 11:31:17 +0800 Subject: [PATCH] ACPI: DMI to disable Vista compatibility on some Sony laptops Linux claims Vista compatibility to the BIOS for a number of reasons, but this brings hard lockup on some Sony laptops. Disable Vista compatibility via DMI for these laptops unless we can figure out what Vista is doing for this platform. http://bugzilla.kernel.org/show_bug.cgi?id=12904 Signed-off-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/blacklist.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/drivers/acpi/blacklist.c b/drivers/acpi/blacklist.c index 09c6980..f6baa77 100644 --- a/drivers/acpi/blacklist.c +++ b/drivers/acpi/blacklist.c @@ -192,6 +192,22 @@ static struct dmi_system_id acpi_osi_dmi_table[] __initdata = { DMI_MATCH(DMI_PRODUCT_NAME, "ESPRIMO Mobile V5505"), }, }, + { + .callback = dmi_disable_osi_vista, + .ident = "Sony VGN-NS10J_S", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "Sony Corporation"), + DMI_MATCH(DMI_PRODUCT_NAME, "VGN-NS10J_S"), + }, + }, + { + .callback = dmi_disable_osi_vista, + .ident = "Sony VGN-SR290J", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "Sony Corporation"), + DMI_MATCH(DMI_PRODUCT_NAME, "Sony VGN-SR290J"), + }, + }, /* * BIOS invocation of _OSI(Linux) is almost always a BIOS bug. -- 2.7.4
