Description of problem:
I've installed FC7T2 + latest rawhide kernel 2.6.20-1.3017.fc7 for x86_64. My system has an Intel Pro1000/MT PCI network card (e1000 module) as eth0 and a Realtek RTL8168b/8111b PCI-E network card (r8169 module) as eth1.
When both cards have a network link they get their IP addresses via DHCP and everything is fine.
When the e1000 card is not connected to the network DHCP fails of course for this card. Afterwards it tries DHCP on the r8169 card and then the system locks hard. I can see a call trace with several lines for the r8169 module on the console but nothing is logged to /var/log/messages.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. have a Intel Pro1000/MT PCI card as eth0 (e1000 module) and a Realtek RTL8168b/8111b PCI-E card (r8169 module) as eth1
2. boot the system with eth0 disconnected from the lan and eth1 connected to the lan
3. both eth0 and eth1 should be set to use DHCP

Now I'm on FC7T3 with todays rawhide kernel and it's gotten even worse. Even if
both network card have a link to the lan the system sometimes locks up hard
while trying to get the DHCP infos for the Realtek card.
Same problem on 2.6.20-1.3056.fc7 ( i686 ) but with only one onboard network card :

Bernd, please try the latest rawhide kernel available. It has a fix for
lockups with r8168 devices. Does it work better for you?
William, I think you probably have a different issue. Could you open a new
bug with the details of the issue you are seeing? Thanks!
John, I'm now on kernel-2.6.20-1.3094.fc7.x86_64 and I can't reproduce the
problem anymore. I rebooted the system several times with the e1000 card
connected and unconnected and got no lock-up so far. Good job.
BTW: Will this fix be in the kernel of FC7T4?
I don't think that is frozen yet, so I assume so.
Thanks for the feedback!

Yes it wasn't exactly the same issue ... but the card works perfectly know with
BTW: What can we do to get this driver into RHES5 ASAP?
Bernd, please feel free to open a bug against RHEL5.
I've opened an RFE-bug against RHES5: 238187
