E1000 nic fails; used to work

[Kent West <westk@acu.edu>]

I've got a fairly new Dell GX260 with an integrated gigabit nic. I 
started out with 2.2.20 (stable), but that didn't recognize the nic, so 
I used Knoppix to download a newer kernel (2.4.18, and all the attendent 
dependencies), and after adding "e1000" to /etc/modules, the network 
started working for me! Yea! I then promptly upgraded to unstable.

That worked for several weeks, until my office mate returned to work, 
and booted into Windows (dual-boot, obviously). Now when I boot into 
Debian, dhcp doesn't find any address, and when I manually run 
"/etc/init.d/networking start" I get errors like "recieve_packet failed 
on eth0" and "network is down". The network works fine from Windows, as 
this email is proof.

I tried another kernel upgrade, this time to 2.4.18-4-686, but the 
network responds the same. I figured I'd try a static address, to see 
what that results in. Here's my interfaces file, and the results.

westk[@garciajo]:/home/westk> cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo eth0
iface lo inet loopback

#iface eth0 inet dhcp

iface eth0 inet static
       address 150.252.161.230
       netmask 255.255.248.0



westk[@garciajo]:/etc/network> sudo /etc/init.d/networking start

Any clues would be appreciated.
