Public bug reported:
I got a 1GB network card and I tried to copy my xen image (30GB), so I run
nc -l 3000 > image.dd
on xen dom0
and tried to send using nc from another remote machine.
The machine crashed after 3-15 seconds. I tried this many many times.
I managed to get bug using netconsole (attached).
