Fair enough. Have you tried disabling tso on the ix's ? That does fix the problem for me, however there is a performance penalty to be paid.
I'm now regressing through the ixgbe drivers - I see there's been changes to how the queues are drained between 9.1 - 10.0, will see if the older ixgbe 2.4.8 works under 10.0 On Fri, Mar 21, 2014 at 1:40 PM, Markus Gebert <markus.geb...@hostpoint.ch>wrote: > > On 21.03.2014, at 15:49, Christopher Forgeron <csforge...@gmail.com> > wrote: > > > However, if you can make a spare tester of the same hardware, that's > > perfect - And you can generate all the load you need with benchmark > > software like iometer, large NFS copies, or perhaps a small replica of > your > > network.
