Odds are you didn't actually do this, just configured them so that they won't pickup a GUA.

U were right :D

These only take effect if you reboot or unload the modules manually.

Tryning not to reboot, when unloading I get the message that the modules is in use. I think that forcing the unload is too dangerouse, read that it might resolve in kernel panic.

I would expect yum to try another address, until one succeeds. Sorry, I don't know why it would not do so.
