Hi, Might be a bit late, but should be noted. We had the same issue on our Testsystem, after upgrading to Debian squeeze. A posting on http://blog.gmane.org/gmane.comp.linux.lvs.user/month=20111101 from Michael Schwartzkopff gave the right hint and led to the solution. Looks like starting some when after kernel 2.6.26, generic-segmentation-offload was introduced and activated by default - at least our NIC - driver: tg3 on Debian squeeze.
So disabling it via ethtool solved the problem. [snip] # ethtool -K eth0 gro off # ethtool -k eth0 | fgrep 'generic-receive-offload' generic-receive-offload: off [snap] Hope this helps.
