Description Arsen Shnurkov 2009-04-19 13:19:50 UTC

I an trying to download large amount of data through NFS share. After a short time network link became unusable on all protocols (ssh, ping, NFS, http).

It happens on the network card which is used to download large amount of data (I have three cards from different vendors).

after 
ifconfig eth2 down && ifconfig eth2 up 
network work again for about two minutes.

nothing is written in /var/log/messages

I use 2.6.29-r1 and willing to make tests on request.

On the same machine I have another bug. 
I don't know are they related or not:

Comment 3 Arsen Shnurkov 2009-04-19 13:28:44 UTC

Also, it is good to learn, how to remove "Tainted" mark :)

Could this be related to the upstream bug:

http://bugzilla.kernel.org/show_bug.cgi?id=12500

Similar traces and same causes. (nic under load)

Yes, the trace message suggests the same as your bug description and that upstream bug looks correct. Will track that. If you want to help further, please see the task I just suggested on the upstream bug :)
