Date: Sat, 06 Oct 2012 19:55:45 -0000 From: Graham Gower X-Patchwork-Id: 189789 Message-Id: <50711961.1010101@gmail.com> To: netdev@vger.kernel.org, Stephen Hemminger Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. 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 --- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html --- skge.c.bak 2012-10-07 13:00:56.000000000 +1030 +++ skge.c 2012-10-07 13:26:03.000000000 +1030 @@ -4143,6 +4143,13 @@ DMI_MATCH(DMI_BOARD_NAME, "nForce"), }, }, + { + .ident = "ASUS P5NSLI", + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "ASUSTeK Computer INC."), + DMI_MATCH(DMI_BOARD_NAME, "P5NSLI") + }, + }, {} };
