Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1124 Lines: 30 I believe I have figured out why the e1000 crashed my machine after .5 - 1 hours: The NIC was over-heating. I measured one of the NICs after the machine crashed with an external (cheap) temp probe. It registered right at 50 degrees C, and this was about 15-30 seconds after it crashed. The dual e1000 NIC I have seems to run much cooler, and has been running at 430Mbps bi-directional on both ports for about 6 hours now with no obvious problems. So, I'm going to try to purchase some heat sinks and glue them onto the e1000 server nics, to see if that fixes the problem. Hope this proves useful to anyone experiencing similar strange crashes!
