Strange problem after restarting network service

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

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
