=======================
Please answer the questions / provide the following info so we can continue debug on our site:
1. do you have a Mellanox Firmware version that works?
2. what kernel version did you use? We had a fix for interface naming issue in Ubuntu-3.13.0-35.61 - that may fix it.

What I think that we need in addition is, take the following info before and after the modules reload:
1. lsmod | grep mlx4
2. grep . /proc/net/bonding/bond*
3. grep . /sys/module/mlx4*/parameters/*
4. ifconfig -a
5. ethtool -i <mlx4_ifs>
6. grep . /sys/class/net/*/* 2> /dev/null

and these we need only once, after the driver was reloaded:
1. provide your /etc/network/interfaces and additional included files if any.
2. dmesg
3. uname -r
4. grep mlx /etc/modprobe.d/*
5. cat /etc/issue
6. ofed_info
=======================

Please note that we will need HP to provide these answers, as they have
the m400 hardware that displays the problem

Title:
  On Mellanox adapter, reboot under Bond mode loses interface

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This is reported at HP in their bug tracker as: QXCR1001386573

  Symptom: Every time reboot under bonding mode in ubuntu14.04, the
  interface eth0/eth2 disappeared, and only bond0 showed up. The
  Mellanox driver needs to reload. Then the interfaces will appeared and
  the bonding function is working fine.

  HP CSI confirmed that the issue can be seen on Anders (m710) with two
  Mellanox Firmware Version: 2.32.1092 and 2.32.5210. Also another
  Cartridge - McDivitt (m400) has similar issue. Other Cartridge with
  Intel NIC solution does not have this problem when doing bonding. Is
  it possible that the issue is about Ubuntu & Mellanox compatibility
  problem?
