A number of Dell systems require an OEM _OSI string "Linux-Dell-Video" as a BIOS workaround to disable RTD3 which causes systems hangs when NVidia graphics cards are installed. The affected Dell systems are with system IDs: 0818, 0819, 0820, 0850, 0851, 086F, 0870, 0885 and 0886. The form of the OEM _OSI strings is defined by each OEMs and is discussed in Documentation/acpi/osi.txt. Signed-off-by: Alex Hung <alex.hung@canonical.com> Signed-off-by: Rafael J.
