Can you check if things improve with v3.8-rc2 after removing : 1. 9ecb9aabaf634677c77af467f4e3028b09d7bcda r8169: workaround for missing extended GigaMAC registers 2. d64ec841517a25f6d468bde9f67e5b4cffdc67c7 r8169: enable internal ASPM and clock request settings
Doesn't help for this problem. However this fixes a second issue for me: In 3.7.1 at startup the link came up after 15 sec.: grep r8169 dmesg.3.7.1 [ 1.956842] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded [ 1.957059] r8169 0000:02:00.0: irq 42 for MSI/MSI-X [ 1.957161] r8169 0000:02:00.0 eth0: RTL8168evl/8111evl at..

[ 13.575452] r8169 0000:02:00.0 eth0: link down [ 13.575475] r8169 0000:02:00.0 eth0: link down [ 15.181317] r8169 0000:02:00.0 eth0: link up In 3.8rc the time increased to 24 seconds: grep r8169 dmesg.3.8.0 [ 1.852546] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded [ 1.852765] r8169 0000:02:00.0: irq 42 for MSI/MSI-X [ 1.852872] r8169 0000:02:00.0 eth0: RTL8168evl/8111evl at...

That's it! This fixes the problem for me! Thanks, Jörg
