Comment 23 for bug 1681909

It came to my attention that this issue still exists; an user report on x84-64 machine confirms that it's not only a ppc64 issue, it's a generic problem due to some NICs behavior; even with link up, they are really not ready to xmit packets. So, I could reproduce this by modifying virtio to mimic this scenario, and I'm working in a solution/quirk on kdump-tools (makedumpfile) package.
