Colony sometimes fails to initialize the networking interface

[vic-quakesrc]

On the latest Ubuntu (Colony #3 + all updates) the network manager sometimes
fails to properly initialize the integrated NIC, meaning no IPv4 address is
present. It's directly connected to an ADSL router with DHCP service running on
it, and apparently Ubuntu sometimes misses the DHCP reply packets (it assigns an
IPv6 address to an interface though, dunno where it comes from - so I manually
disabled IPv6).

Workaround:
1. Run Gnome Network configuration utility and set the interface to eth0 for
that card.
2. Deactivating the interface in that utility doesn't help - program just
freezes. As a workaround I select the interface, press 'Configure', disable,
then reenable it there and press 'OK'. The utility freezes too in this case, but
the interface now has a valid IPv4 address.

Hardware:
A8N-SLI (nForce4 chipset), AMD64 3200+

Kernel:
2.6.12-8

I don't have such problems on WinXP (it comes with IPv6 disabled by default,
anyway). I can't recall if Ubuntu 5.04 had such problems though.

Note, I don't think the main bug is related to GNOME itself: inability to
properly assign an IP address, recieved from a DHCP server is somewhat a general
system bug. Network Manager freezing after pressing 'OK' button is clearly a
GNOME bug though.
