[Xen-devel] RE: win-pv assertion failed while migrating

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I've found a race in xennet that could cause the problems you are seeing

think you can build from source. If not, I should be able to upload some
binaries tomorrow. Please let me know how your testing goes.
