PE6650 Just Hangs

We have just bought several PE 6650's preloaded with Red Hat AS 2.1 and the
Broadcomm onboard NIC.  Being a complete newbie to Linux (1 week and
counting) we have had to pester both Dell and Red Hat for technical support
numerous times.

During the course of these support calls we have learned that not only does
Dell not support the tg3 driver, Red Hat won't support the Broadcomm driver,
which made for some very interesting discussions as we tried to configure
these servers.

Trying to learn a new OS on the fly is challenging enough without having
these "Catch 22" events occur.

My $.02 worth.

The only problem with the tg3 driver is that it is not officially supported
by Dell.  If anything goes wrong the Dell techs will tell you that you are
not compliant.  The Broadcomm crap cards have a long history of proprietary
problems, like sharing the code with those writing the drivers.  

In our shop, and in several locations, we replaced the on board crap with
Intel Pro 1000's and they run great.  No more system lockups due to the
network.

**HINT HINT HINT Dell people**

Dell, IMHO, needs to start selling boxes designed for Linux and stop selling
windows boxes that hobble running Linux. Oh yeah, and try building more than
two servers (6650, 2650) while you are at it.

Jay, 
 
Our 6650 issues may be unrelated, but FWIW I am running version 6.2.11 of
the bcm5700 driver and we are still getting frequent lockups with our
systems. I just switched one of our 6650's over to tg3 this morning, and
will let you know if this makes a difference with the lockups. 
 
I have yet to try load testing the interfaces, but based on your ability to
reproduce the issue I am now very inclined to run such a test. Thanks for
posting back your results. 
 
  --Anthony

	Thanks for the info.
	
	We used Netperf to hammer the Broadcom gig port.  In about ten
minutes the
	server went bye-bye... no keyboard, no video, no network.
	I feel a lot better now that we can reproduce the problem. We had a
	conversation with a Dell tech earlier. He suggested installing the
Broadcom
	BCM5700 Linux Driver V. 6.0.5.
	
	We'll give this a shot and see how it goes.
	
	If anyone else has tried this please share your experience.
Everything I've
	read so far leads me to believe this solution is too easy.
	
	Thank You,
	
	Jay

	tg3 in latest RHL errata kernel should be stable.
	
	(deja vu) There are lots of NET tools:
	
	NetPIPE   http://www.scl.ameslab.gov/netpipe/
	Netperf   http://www.netperf.org/
	Iperf     http://dast.nlanr.net/Projects/Iperf/
	gensink   http://jes.home.cern.ch/jes/gensink/
	
	TTCP      http://ftp.arl.mil/~mike/ttcp.html
	New TTCP  http://www.leo.org/~elmar/nttcp/
	nuttcp    ftp://ftp.lcp.nrl.navy.mil/pub/nuttcp/
	
	net-stress - http://colorfullife.com/~manfred/TestApps/
	
	pktgen -
ftp://robur.slu.se/pub/Linux/net-development/pktgen-testing/
	
	I like NetPIPE and nuttcp(latest son of ttcp).
