Public bug reported:
After resuming from being suspended, I no longer have a working Network. I
need to run the following commands to bring it back up:
sudo ifdown eth0
sudi ifup eth0.
Note that the ifdown command reports the following two errors:
RTNETLINK answers: No such process
SIOCDELRT: No such process
Of course, I expected the network to work after resuming. This worked
as expected with Ubuntu 7.10. I just updated yesterday to 8.04
I am using the following ubuntu version:
Description: Ubuntu hardy (development branch)
Release: 8.04
Note that I have KDE installed and am using that, not that that should
matter any.
I have attached the output of dmesg below. I cleared its contents (sudo
dmesg -c) just before suspending.
Output of ifconfig (after runninf ifdown and ifup) follows:

contents of /etc/network/interfaces follows:

# and how to activate them. For more information, see interfaces(5).
# The loopback network interface

Please let me know what other info I can provide that can help debug this. I
am very computer literate, so I shoudl have no problems experimenting if you
have any ideas of what to try.
