Hi,
I've got a small problem with 2.6.18-rc5-git2.
I've got a vlan setup on eth0.20, eth0 does not have an IP.
When I attempt to reboot or halt the machine I get the following message from the loop in net/core/dev.c::netdev_wait_allrefs() where it waits for the ref-count to drop to zero. Unfortunately the ref-count stays at 1 forever and the server never gets any further.
unregister_netdevice: waiting for eth0.20 to become free. Usage count = 1
I googled a bit and found that people have had similar problems in the past and could work around them by shutting down the vlan interface before the 'lo' interface. I tried that and indeed, it works.
Any idea how we can get this fixed?
