I checked HWADDR in the ifcfg-ethX files and they are correct, as are the entries in hwconf now. However when I boot, it still boots up eth1 (PCMCIA) as eth0, then tries to boot up eth1 as eth1, which it can't rename it because the device is busy. I haven't been able to replicate this outside of a clean boot, every time I boot I have to "ifconfig eth0 down" (standard ifdown doesn't work because HWADDR is set and the wrong card is currently eth0). Then every time I use ifup, ifdown or init.d/networking it works fine. I also checked modprobe.conf, I can remove all kernel modules and do "modprobe eth0" and it loads the right driver and the right card is eth0. Here is the error from my boot.log
