+description = """When using sunhme, sometimes on receiving traffic (and doing disk IO?) it will get slower and slower until it becomes entirely unresponsive, which does not happen on the real hardware I have sitting next to me (Sun Netra T1, running the same OS+kernel, though not the same image)
+
+virtio-net-pci does not, so far, demonstrate the problem, and neither does just sending a lot of traffic out over the sunhme interface, so it appears to require receiving or some more complex interaction.
+
+It doesn't always happen immediately, it sometimes takes a couple of tries with the command, but when it does, it's gone.

+Output logged to console below."""
