Hello list, After installing SuSE 9.3 which is with default kernel linux-2.6.11.4-21.11, command "rcnetwork restart" work correctly, i.e. vlans are up and running. But 2.6.11 has probrlems with removing vlan "Unregister_netdevice: waiting for vlan135 to become free" without any traffic trough this device. We was changed the kernel version with 2.6.16.14, but here we have this problem. After reboot the system everything seems to be normal, but after restarting network service "ip" shows interesting sequences of devices: # ip addr ls 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: eth0: <BROADCAST,MULTICAST,UP> mtu 1504 qdisc pfifo_fast qlen 1000 link/ether 00:50:45:bb:d6:d4 brd ff:ff:ff:ff:ff:ff inet 169.254.100.105/24 brd 169.254.100.255 scope global eth0 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:50:45:bb:d6:d5 brd ff:ff:ff:ff:ff:ff inet 192.168.21.2/24 brd 192.168.21.255 scope global eth1 874: vlan135: <BROADCAST,MULTICAST,UP> mtu 1504 qdisc noqueue link/ether 00:50:45:bb:d6:d4 brd ff:ff:ff:ff:ff:ff inet 192.168.23.250/30 brd 192.168.23.251 scope global vlan135 937: vlan905: <BROADCAST,MULTICAST,UP> mtu 1504 qdisc noqueue link/ether 00:50:45:bb:d6:d4 brd ff:ff:ff:ff:ff:ff inet 192.168.151.130/30 brd 192.168.151.131 scope global vlan905 ******************************************************* I was check many ways different config-s, but in the network area they are similar and CONFIG_VLAN_8021Q=m. I cannot understand where is the problem, in the kernel, in the distribution or between the chair and the keyboard, but any help is great appreciated. Thanks Best regards
