I can't prove that the network-related soft lockups I'm seeing on the x330's are the same soft lockups related to filesystem damage we saw on the Netengines -- we stopped using Netengines for Xen 3 when we hit that (they run Xen 2 fine). Now that I know what to look for, I'll go back and re-create the Xen 3 environment on the Netengines so I can reproduce the problem there. > Have you tried using -unstable and hence xen's new scheduler?

Haven't tried unstable yet, since this is for the production infrastructure for my family's business; am in the process of rebuilding with testing changeset 9762 though. (is that really tip? hg log says Jun 29th for that changeset, even after a pull...) Thanks again, Steve -- Stephen G.
