Description Hans-Helmar Althaus 2007-02-21 00:57:00 UTC
Description of problem:

the forcedeth driver you are using in rhel4 fails to
setup link on most gigabit switches

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

2.6.9-42 with forcedeth 0.41

How reproducible:

Connect for example a hp xw9400 on a hp procurve switch
Actual results:

no traffic

Expected results:

normal communication

Additional info:

the link light will go on, but the
RX counter remains on zero

the current driver aviable from nvidia
or plain vamilla kernel works.

Comment 1 Andy Gospodarek 2007-03-12 21:37:15 UTC
I have an xw9300 and tested it today without any problems.  Can you send output
from 'ethtool ethX' for that interface?

A sysreport might be nice as well, but we can start with the ethtool output if
you like.

Comment 2 Hans-Helmar Althaus 2007-03-13 07:51:02 UTC
I am sorry i have installed the driver provided from nvidia because we need this
machine working. With this driver or attached on a 100 MBit ethernet i did never
see any problems for now. The problem for me is that i have to hack the
redhat.initrd for pxe-installation of this workstation (i have to unpack the
initrd and to replace forcedeth module). The problem is known to nvidia and hp
(xw9400 and maybe also fujtsu-siemens v840) - please ask anybody there if you
dont trust me, i can provide you a contact person if you like.

The output of ethtool (eth0 is a nvidia interface but the driver is the on from
nvidia webside, forcedeth 0.59 !! ):

[root@fsc-amd-2 ~]# ethtool eth0

Comment 3 Andy Gospodarek 2007-03-13 13:05:56 UTC
Thanks for the feedback.  Please send me your contact person at HP, so I can get
more detail about which switches have this problem.

I have not heard complaints about the xw9400 and forcedeth on 4.4 and I've not
personally experienced and problems with my xw9400 and an unmanaged D-Link
gigabit switch, so I would like to understand what devices won't link up with
this hardware.

Comment 4 Andy Gospodarek 2007-03-14 18:40:18 UTC
Good news.  I played around some more and noticed that eth0 does have problems
linking up at gigabit speeds and confirmed that this is fixed in our latest
development kernels (though I did find another problem).  

Closing this as a duplicate of BZ 197797.
