I am hitting a bug that manifests in an unregister_netdevice error message. After the problem is triggered processes like ifconfig, tunctl and route refuse to exit, even with killed. And the only solution I have found to regaining control of the server is issuing a reboot. The server is running a number of tap devices. (It is a UML host server running the skas patches http://www.user-mode-linux.org/~blaisorblade/). Regards, Peter # uname -r 2.6.11.7-skas3-v8 unregister_netdevice: waiting for tap24 to become free.
