This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.html Signed-off-by: Graham Gower Signed-off-by: Jan Ceuleers --- I am resubmitting Graham's v4 patch hoping that doing so will avoid further frustration while still getting this fix into the tree. I have not tested this; I don't have the hardware. It compiles though. drivers/net/ethernet/marvell/skge.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/drivers/net/ethernet/marvell/skge.c b/drivers/net/ethernet/marvell/skge.c index 5a30bf8..05b3c83 100644 --- a/drivers/net/ethernet/marvell/skge.c +++ b/drivers/net/ethernet/marvell/skge.c @@ -4153,6 +4153,13 @@ static struct dmi_system_id skge_32bit_dma_boards[] = { DMI_MATCH(DMI_BOARD_NAME, "nForce"), }, }, + { + .ident = "ASUS P5NSLI", + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "ASUSTeK Computer INC."), + DMI_MATCH(DMI_BOARD_NAME, "P5NSLI") + }, + }, {} }; -- 1.7.9.5
