Problem Description:
I've reported this problem about 3 months ago (to Arch devs) and at that time it disappeared. I have a DELL pc with an Intel QUAD Core processor and Nvidia graphics card (9600GT). My machine has two network cards (one wifi (Broadcom) and one normal cable (Realtek)). In the last two or three days now I haven't had any internet/network connection and udev takes like 90 seconds (normally it takes a second) to start up. When I boot my machine right after grub I get these warnings

RTNL: assertion failed at net/core/fub_rules.c (625)
RTNL: assertion failed at net/ipv4/devinet.c (1045)
RTNL: assertion failed at net/ipv4/imgp.c (1348)
RTNL: assertion failed at net/ipv4/imgp.c (1199)

I first thought my machine had switched the order of dependence it loads the network cards (eth0=wifi, eth1=cable) to (eth1=wifi, eth0=cable). So I tried to change the order in wicd but that doesn't help. So something is broken again in Arch Linux. I've haven't making ANY changes to my system all other than updating my machine when updates are available (using KDEmod 4.2.1). So I have no clue what the problem is, if it's the kernel or udev or klibc-udev. I just know this is very very annoying.
