Hello list, I have a problem with two vlan interfaces on one NIC under load about 120-140mbit. My network script is 'ip' based (not 'ifconfig') and when I do ifdown-ifup, very often I have the following: Jul 10 20:49:41 Anakin kernel: unregister_netdevice: waiting for eth0.778 to become free. Usage count = 1 Jul 10 20:50:12 Anakin last message repeated 3 times Jul 10 20:51:12 Anakin last message repeated 6 times Jul 10 20:52:12 Anakin last message repeated 6 times Jul 10 20:53:12 Anakin last message repeated 6 times Jul 10 20:54:12 Anakin last message repeated 6 times After this the system hangs up. My question is: Can I avoid this situation somehow? And where is the problem in my NICs: 3Com Gigabit NIC (3C2000) or in vlan module? The current kernel version is 2.6.12.2, and the problem is from 2.6.9. Any suggestions are welcome thanks in advance best regards
