unable to configure network connection using wired ipv4 manual method

[josephpatterson]

I loaded the 9.10 beta version of ubuntu on my dell E6500 laptop and am unable to configure a network connection. When I select system->preferences->network connection->wired->eth0->edit->ipv4 settings->method->manual and then add an address and netmask and gateway and dns servers and then select apply and enter the needed authentication, the requested network connection is not setup. The tool forces the interface back to DHCP and /etc//NetworkManager/system-connections/eth0 contains the line autoconnect=true (i.e., the manual address is forced back to DHCP). Repeating the above menu selections reveals that the method remains at Automatic (DHCP).

Moreover, when I run appropriate ifconfig and route commands as root and create an /etc/resolv.conf file with nameserver lines for DNS servers to overcome this deficiency in the network connection tool, I am able to access the local network, but the routing to the outside world does not work (i.e., /etc/resolv.conf is being ignored). Linux has never done this previously. Why is ubuntu trashing fundamental linux procedures? No matter how many conveniences you implement, this sort of change is bad.

The above problem still exists after running the command "sudo /etc/init.d/apparmor stop" (i.e., this fix for an earlier bug does not help).

I am attaching a buglogs file with the output of the following commands:
lsb_release -rd
uname -a
cat /proc/version_signature
lspci -nn
lspci -vnvn
dmesg

I have same problem on ASUS k52jr laptop.
I try install xubuntu 9.10 i386 and have no problem with network - all works fine.
Under windows 7 all works fine too.
But under ubuntu 9.10 amd64 - not any wired connection aviable.
When I manualy setup /etc/network/interfaces and /etc/resolv.conf. After that ifconfig show right IP properties but network still won't work.

Command "sudo lshw -C network" show:
...
Ethernet interface: JMC250 PCI Express Gigabit Ethernet Controller
bus info: pci@0000:05:00.5
logical name: eth0
... etc

Hi josephpatterson,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 449529

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
