Created attachment 92751 [details] lspci -nnvv After rebooting from Windows XP to Gentoo Linux the NIC acts as dead (no LED light at all). NIC works on a cold boot without problems. The problem is described at ArchWiki: https://wiki.archlinux.org/index.php/Network_Configuration#Realtek_no_link_.2F_WOL_issue NIC info: Windows: NIC: Realtek RTL8139/810x Family Driver version: 5.719.325.2009 Linux info: DMESG: 8139too RealTek RTL8139 Kernel built-in driver: RealTek RTL-8129/8130/8139 PCI Fast Ethernet Adapter Tried Kernel version 3.5.7 & latest 3.7.4 (gentoo-sources) More at: http://superuser.com/questions/546441/no-internet-in-linux-after-rebooting-from-windows/546621 I can reproduce this everytime I disable "Shutdown WOL" property in Realtek's NIC driver on Windows and then rebooting machine. DMESG output with and w/o working NIC is same except some differences in timing..
