Was the same X520 used in all of those systems? Do you have a different X520 to try? > mcelog is empty. The 5018D-MTF Event log has nothing either.

The first message had a time stamp of 320 seconds, and then there is a new kernel booting. Is this the crashkernel being started? A kernel running long enough to get to your iptables rules should have produced a lot more messages than what I am seeing. Can you try running with no crashkernel option and while you are at it, please remove the quiet option. The last thing you want when troubleshooting is for things to be quiet. -- Mark Rustad, Networking Division, Intel Corporation
