TCP Stack Crashes Dell Broadcom TOE SNP BCM5708C

I am testing the Broadcom problem on several Dell 1955 Blade servers. There
appears to be a problem in the TCP Stack when running the Broadcom 5708c
adapter With or without the SNP (912222) Component. I recently learned the
912222 patch installs SNP and enables TOE at the OS level.
Basically what happens is the network adapter will loose the ability to
communicate with the network. In the most extreme cases it is necessary to
log on locally and reboot the server. After rebooting the server it operates
as normal for several days then repeats.
In testing the same configuration on an HP Server with Inter Nic there is no
duplication of error.

Back to the Dell 1955 with broadcom.
I have installed the latest broadcom/dell Critical driver update patch
12/21. Installing the patch solved some of the problems related to servers
completely dropping off. Problems remain on servers with high utilization.
The server will drop the network connection no error indicated on the network
switch Cisco 2950. The server does not record a BSOD although if I log in as
an admin at the console the login indicates an unexpected shutdown. Looking
at the logs there are no indications of error prior to the crash. The servers
are rebooted daily.
This error is present with or without the 91222 patch.

Same Adapter Same os Same Server type of Dell Server 1955 running the
Dell/broadcom 4/07 code no TOE is stable.

Dell has been very little help with this problem.

DELL PowerEdge 1900 - Broadcom BCM5708C - Problem

Hallo,
i have just invest in an DELL PowerEdge 1900 - Broadcom BCM5708C to be use as an Windows-Terminal-Server. The Netinverface Broadcom BCM5708C make the same Problems as the system of you.

Just the dinstall of the TOE-Sytem makes no result.

Have you any other information to solve the problem ?

The DELL-Server with the Broadcom-interface just make in cases so many trafic to the net, that the domancontroller stoped. I think, to invest in an several new netinterface-card for the DELL-Server und cancel the Bradcom-Interface.
