Two servers were running linux-4.4.2 for many months, both with 10Gbase-T NICs connected to the same switch, without any such outage. Both servers were recently upgraded to linux-4.6.1, and one of the servers so far twice showed this "IO_PAGE_FAULT" symptom within a period of ~ 7 days. The hardware of the two servers is the same except for the model of the Intel 10Gbase-T NIC: The server with the two fails runs a fairly new Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01) while the other server (without symptoms so far) runs a much older Intel Corporation 82598EB 10-Gigabit AT Network Connection (rev 01) both using the same ixgbe driver module. (Since both servers are working as a shared-nothing-cluster, they pretty much do the same.)
