Description Clay Cooper 2002-01-10 14:09:31 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.4) Gecko/20011019

Description of problem:
Bordeaux w/ 64GB ram, A02 Bios, broadcom nic slot 8, w/ 7.2 Itanium Gold
installed.  

Starting 3 instances of nttcp on a gigabit line with the following parameters:

./nttcp -T -n128  -l262144 -w256 $1
./nttcp -T -n128  -l262144 -w256 -r $1 -t
And then...
Kernel panic:  Aiee, killing interrupt handler!
In interrupt handler -- not syncing

This has been reproduced twice so far.  Once within an hour.  The second time
occurred overnight.  I have previously tested this driver several times without
issue in previous release candidates.

It is probable that, although using multiple instances of nttcp to verify the
bandwidth, I did my sustained testing with only one instance. 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  Itanium Gold on a bordeaux with a broadcom 5701 nic
2.  Begin multiple nttcp instances on a gigabit line
3.  Look for kernel panic in interrupt handler

That driver is v2.0.28.  Broadcom has made available to Dell v2.0.34 which the 
SNaC team is testing.  Clay, can you get that from Thomas and try?

Comment 2 Clay Cooper 2002-01-11 13:43:31 UTC
Reproduced kernel panic twice w/ bcm5700 v2.0.34



Comment 3 Matt Domsch 2002-01-11 21:12:47 UTC
Until this driver is cleaned up then (either by Broadcom or RH), Dell won't 
offer the Broadcom cards on the PowerEdge 7150.

Comment 4 Michael K. Johnson 2002-08-06 15:26:19 UTC
Matt, do you know if Broadcom's more recent versions of their driver
fix this problem?

Comment 5 Jeff Garzik 2002-10-25 17:02:08 UTC
Can you please test nttcp and the latest "tg3" driver, to see if this problem
has been resolved?

Actually, my preference would be to close this bug and open a new one if tg3 has
a problem, since bcm570x driver is so grotty.  But I will leave this bug open
for a while, until I get a response to this comment at least.


Comment 6 Jeff Garzik 2002-12-09 19:32:30 UTC
No response on this bug in a long time, so I'm going to close it.

Please re-open if tg3 driver version 1.2 does not solve this problem.
