That said I thought the NMI thing was fixed recently, which might have gotten you better debugging on the rcu problem.This went into v3.12-rc1 (commit 6efa20e). Steven, can you try your test with newer kernels that have this fix? With it we should be able to see where the stall is happening.Sadly I can't easily rebuild this to 3.12. Is it possible to get a version / patch / commit that will work with 3.11.x? I am not sure I understand what you are asking for. A backport of the patch to 3.11.x so that you apply it on top of your sources and build it yourself? -boris _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
