Description of problem:
I have 6 dual Xeon 5160 compute nodes with Supermicro X7DVL-E motherboards
These boards have onboard Intel 82563EB NICs (PCI ID 8086:1096). When I first
installed them, I was running U4 (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 U5 (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.

Steps to Reproduce:
1. Install kernel 2.6.9-55
Network is highly unreliable (df hangs on NFS shares, can't do YP lookups, etc)
According to my server vendor, this problem still exists in RHEL5 (which also
A major update to e1000 is planned for the next update.
You can always try my latest test kernels (they generally contain experimental
net-driver fixes and are regularly updated):
For this case, you can also check the kernels available here:
Since they contain kernels that are close to the ones that will be released with
the next RHEL4 update.
Can you give either of those 2 kernels a try?
Since filing this bug I've switched jobs and moved across the country, although
I do still consult for that group. I'll try to give those kernels a shot ASAP.
Given the driver version is one I've had work, I'm hopeful.
This bug has seen no activity in quite a while, so I can only presume it is no
longer a problem. If there is still an issue that needs to be resolved, please
re-open this bug and I will be happy to help resolve it. Thank you.
