I've recently updated my home server from OpenSuse 10.3 to Lucid Server.
I replaced the motherboard with an Intel DQ35JO that I had lying around. I've dropped in a Core 2 Quad and 4Gb RAM.
Additionally I added a 3Ware/AMCC 9650-2LP RAID controller for the disks, which runs off one of the PCI-E x1 slots.
From the "old" server I brought across an Intel Pro 1000 PT Dual Gigabit PCI-E Server Adaptor which is utilising the mobo's PCI-E x16 slot. On the old motherboard (an Asus) this worked without issue.
The problem I'm having is that the NIC seems to be going into some kind of sleep mode once other computers on the network disconnect. Booting up any of the machines directly attached to the same gigabit hub (a Netgear ProSafe GS116) reinstates the connection.
The server logs don't show any indication that that the network link is dropping at any point - it just seems to be waiting for a signal from any LAN-connected device. If I try connect using any wireless devices through the wireless router (Netgear DGN2000) I get no response.
Once it's up and running it works flawlessly - but I didn't have any of these problems under OpenSuse with the older motherboard.
It helps - the hub is connected to the router by a single cable. All other wired network connections are made through the gigabit hub. Internet and wireless links are made through the router via the single link.
The server is used for web (public facing development server), emails (SMTP/IMAP), NFS/Samba (internal network only) and VPN.
It really is driving me mad - I'm considering replacing the motherboard to see if that has any effect so any help you guys could give would be REALLY appreciated.
Edit: If forgot to mention it's using the 1.0.2-k2 driver. I've downloaded the latest e1000e driver 1.2.8 - I'll install that later and see if it makes a difference. I'll post the result on here in case anyone else has a similar problem....

If at first you don't succeed, call it v1.0
