Upgraded a Red Hat 7 machine with an Accton SMC2-1211TX network card. Guiness treated this card as an RTL8139 in /etc/modules.conf After the upgrade eth0 failed: (from /var/log/messages) Feb 1 14:25:22 nutmeg modprobe: modprobe: Can't locate module eth0 Feb 1 14:25:22 nutmeg sysctl: net.ipv4.ip_forward = 0 Feb 1 14:25:22 nutmeg sysctl: net.ipv4.conf.all.rp_filter = 1 Feb 1 14:25:22 nutmeg sysctl: kernel.sysrq = 0 Feb 1 14:25:22 nutmeg sysctl: error: 'net.ipv4.ip_always_defrag' is an unknown key Feb 1 14:25:22 nutmeg network: Setting network parameters: succeeded Feb 1 14:25:23 nutmeg network: Bringing up interface lo: succeeded Feb 1 14:25:23 nutmeg modprobe: Note: /etc/modules.conf is more recent than /lib/modules/2.4.0-0.99.11/modules.dep Feb 1 14:25:23 nutmeg modprobe: modprobe: Can't locate module eth0 Feb 1 14:25:23 nutmeg ifup: Delaying eth0 initialization. Feb 1 14:25:23 nutmeg network: Bringing up interface eth0: failed The entry in the Guiness /etc/modules.conf was: alias eth0 rtl8139 Changing /etc/modules.conf in Fisher to: alias eth0 8139too solved the problem.
We (Red Hat) should really fix this before next release
Please post 'lspci -n' and 'lspci -v' lines regarding your NIC.
The problem is that the module changed names, and we don't migrate it currently rtl8139 changed to rtl8129 or 8139too.
For some reason my rtl8159 was recognized with the new driver - 8139too - and was set up properly but the second ether card, a linksys lne100tx v4, was not found or setup during install - ASUS k7v, 750 Athlon, Matrox G400, SB Live, 30 MB IBM 75GXP.

This should be fixed with the combination of kernel-2.4.0-0.99.25 and kudzu-0.93-1.
