##### Steps for reproduce #####
This is my /etc/network/interfaces file:
auto lo
iface lo inet loopback
auto openibd
iface openibd inet manual
pre-up /etc/init.d/openibd start
pre-down /etc/init.d/openibd force-stop
auto bond0
iface bond0 inet manual
pre-up ip link add bond0 type bond || true
pre-up ip link set bond0 down
pre-up ip link set bond0 type bond mode active-backup
arp_interval 2000 arp_ip_target 10.36.0.1 arp_validate 3 primary eno1
pre-up ip link set eno1 down
pre-up ip link set eno1d1 down
pre-up ip link set eno1 master bond0
pre-up ip link set eno1d1 master bond0
pre-up ip link set bond0 up
pre-down ip link del bond0
auto vmbr0
iface vmbr0 inet static
address 10.36.128.217
netmask 255.255.0.0
gateway 10.36.0.1
bridge_ports bond0
bridge_stp off
bridge_fd 0
I execute these commands:
wget
http://dl-cdn.alpinelinux.org/alpine/v3.7/releases/x86_64/alpine-virt-3.7.0-x86_64.iso
-O alpine.iso
qemu-system-x86_64 -boot d -cdrom alpine.iso -m 512 -nographic -device
e1000,netdev=net0 -netdev tap,id=net0
And after few moments I have hang kernel, and theese messages in
console:
[74390.187908] mlx4_core 0000:11:00.0: bond for multifunction failed
[74390.486476] mlx4_en: eno1d1: Fail to bond device
