Yes, I noted originally that this does allow you to move big files around. However, it causes all sorts of other things to break since TCP checksumming is needed to make sure all the packets are correct. So it doesn't effectively leave you with a usable system to do the ethtool trick. -- networki

I have corresponded with one of the Xen devs and he suspects the problem is in the netfront module. He reviewed the netback module code and it seemed right to him. I would hope that Ubuntu devotes a little bit of resources to this issue since it is biting hard to some people that have deployed Ubu

I haven't been able to solve this problem but at least mitigate it. Use the 'rate' directive in the configuration files for all the domUs, to limit the network rate. I also used Shorewall's QoS to limit the download traffic to a value lower than our maximum for the public interface for one of our

Jürgen - Yes, but as noted, doing the ethtool -K eth0 tx off rx off trick turns off tcp checksumming, which then causes all manner of other things to break horribly. I find it pretty sad that this bug is still here with 8.10 out. This makes Xen basically unusable for a lot of situations. :( --

Hi all and Chris, I don't use Xen, the tg3 driver or something else produces this error, too. Yesterday I have found out that disabling AND reenabling checksum validation with 'sudo ethtool -K eth0 tx off rx off; sudo ethtool -K eth0 tx on rx on' fixes the error, too! Another notebook (HP 530)
