I can confirm the same or similar problem. When copying large files over the network (ethernet, cifs mounted share) after a few seconds to a few minutes the system hangs with kernel panic (blinking keyboard lights). This happens all the time and I never managed to copy more than a couple of GBs.
I did a copy from the console and managed to get a picture of the panic. Unfortunately shift-pgup was not working so it is not the whole dump.
