delay this

My Thinkpad T30 had a longtime issue where it would delay for 30 seconds after loading the network card on every boot. I never bothered to debug it until last night, which really makes no sense because I've now got a T61 and (very soon now) a Dell Mini-10 which together obviate the T30 entirely; nevertheless, I'm loyal to this little machine because it's still pretty great.

The issue started after a dist-upgrade several months (or more) ago, so I was thinking it was either the new kernel or maybe udev. After following a couple dead end leads (mostly regarding problems with the Cisco Aironet 802.11 card), I found a couple discussions about udev trying to rename the network cards but getting confused about the dual nature of the Aironet device (i.e., wlan0 and wmaster) and trying to just wait it out. The solution is simple: rm /etc/udev/rules.d/*persistent-net.rules to clear out stale entries from earlier versions of udev.

Note that since I use ifrename I don't care about having persistent network interface names assigned by udev. If you do, your solution may involve deleting this file and then editing the newly created one after a reboot so that your network cards are assigned the right names.

More discussion on this:

Hopefully someone will find this useful.
