It still sounds like being caused by the same changes. Although having the guest and dom0 running the same kernel version should not cause it. At least the problem with different definitions/allowance of number of frags should get resolved by the following patch (IIRC there were actually some other changes to netback/netfront queued along).
Author: Wei Liu <wei.l...@citrix.com> Date: Mon Apr 22 02:20:42 2013 +0000 xen-netback: coalesce slots in TX path and fix regressions commit 2810e5b9a7731ca5fce22bfbe12c96e16ac44b6f upstream. The change above was queued upstream for 3.2.47. This week starts a new update cycle, so end of this week, or early next week, there should be new kernels available in the proposed pocket to try. I would wait for test results using those before looking further into details. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1162924 Title: bug disabling Xen guest interface To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1162924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
