From 7a9810e7bd99c922d9cedf64dbaa5ef6be412295 Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Thu, 17 Jul 2014 12:55:40 +0900 Subject: r8169: Enable RX_MULTI_EN for RTL_GIGA_MAC_VER_40 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ethernet port on my ASUS A88X Pro mainboard stopped working several times a day, with messages like these in dmesg: AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0 domain=0x001e address=0x0000000000003000 flags=0x0050] Searching the web for these messages led me to similar reports about different hardware supported by r8169, and eventually to commits 3ced8c955e74d319f3e3997f7169c79d524dfd06 ('r8169: enforce RX_MULTI_EN for the 8168f.') and eb2dc35d99028b698cdedba4f5522bc43e576bd2 ('r8169: RxConfig hack for the 8168evl'). So I tried this change, and it fixes the problem for me. Signed-off-by: Michel Dänzer Signed-off-by: David S.
