Comment 2 for bug 449529

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
