Hello, With kernel 3.15, I do not recall having any issues, with 3.19, I am getting a kernel crash when I copy files over NFS from machine A to B. Is this a known issue?
I suspect it has to do something with this: Feb 27 09:31:20 remote-host [ 15.745342] dmar: DRHD: handling fault status reg 2 Feb 27 09:31:20 remote-host [ 15.745361] dmar: DMAR:[DMA Read] Request device [04:00.0] fault addr 0 #012[ 15.745361] DMAR:[fault reason 06] PTE Read access is not set Logs from netconsole during kernel crash: Feb 27 09:31:19 atom kernel: [ 2296.410022] ixgbe 0000:01:00.0 eth4: NIC Link is Up 10 Gbps, Flow Control: RX/TX Feb 27 09:31:19 remote-host [ 15.138220] ixgbe 0000:86:00.0 eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX Feb 27 09:31:19 remote-host [ 15.138370] IPv6: ADDRCONF(NETDEV_CHANGE): eth2: link becomes ready Feb 27 09:31:20 remote-host [ 15.565505] systemd-logind[3863]: Failed to start user service: Unknown unit: user@1000.service Feb 27 09:31:20 remote-host [ 15.569093] systemd-logind[3863]: New session c2 of user user.
