    <thetext>Конфиг интерфейсов следующий:
 - eth0 и eth1 объеденены в группу с помощью модуля bonding;
 - интефейс bond0 настроен как 802.1Q-транк (пропуск VLAN&apos;ов на коммутатор);
 - добавлен VLAN200 (имя интерфейса bond0.200)

Далее:
# ip link set bond0.200 name vlan0200
Segmentation fault

# dmesg
....
bonding: Warning: Cannot create /proc/net/bonding/&lt;NULL&gt;
