I have 6 dual Xeon 5160 compute nodes with Supermicro X7DVL-E motherboards
These boards have onboard Intel 82563EB NICs (PCI ID 8086:1096) and the
systems are all running CentOS 4. When I first installed them, I was
running CentOS 4.4 (kernel 2.6.9-42.0.x), which included version
e1000-7.0.39. The network interfaces were very unreliable -- they would
randomly stop and then re-start passing traffic. I downloaded version
e1000-7.3.20 from intel.com, and they worked just fine.
With the release of CentOS 4.5 (kernel 2.6.9-55) and its inclusion of
e1000-7.2.7, I decided to give the stock driver a try again, but it had
the same issues. Again, upgrading to a more recent version from intel.com
(e1000-7.5.5 in this case) fixed the problem.
I'm planning on moving these systems to CentOS 5 shortly (kernel
kernel-2.6.18-8.x), but it too includes e1000-7.2.7.
Has anybody else seen this issue? I'm wondering whether it is motherboard
specific or if it's an issue with the NIC itself.
