Description Hans-Helmar Althaus 2007-02-20 19:57:00 EST
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.

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.

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 Settings for eth0: Supported ports: [ MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: externel Auto-negotiation: on Supports Wake-on: g Wake-on: d Link detected: yes

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.

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).
