Hi everyone!
I just recently updated my server machine to kernel 3.2.1 (was 2.9.39). As a result I'm experiencing network problems. I have 2 Broadcom 5721 NICs installed that did run smoothly until now. Both NICs run in the same subnet and this wasn't a problem in the past.
Now I observe very long response times while accessing the internet, i.e. when I do http or imap calls; I even get time outs. And remote ssh connections are completely broken.
I can fix all this by simply shutting down one of the eth devices. If I do everything returns to normal.
The question is: What do I have to do to get both eth devices up and running again? Any Ideas?

Um well. That one 6 must have gone upside down. How could that happen?! ;)
I surely meant 2.6.39 not 2.9.39. I apologise.

I assume you had these nics bonded?

Please post your output of the following:

Code:
cat /etc/conf.d/net


Code:
cat /etc/udev/rules.d/70-persistent-net.rules


Code:
ifconfig


Code:
ls -altr /etc/init.d/net.*

For some reason I did not bond them. However, I just did and it solved my problem.
Many thanks for the hint. :)
