Bug#338973: unregister_netdevice: waiting for vpn0 to become free. Usage count = 23

[Marc Lehmann <debian-reportbug@plan9.de>]

Package: linux-image-2.6.14-2
Version: 2.6.14-2
Severity: important


The same bug as reported against earlier debian kernels (#323860) still
persists with 2.6.14, and does not happen with my own compiled kernels.

This happens whenever I want to upgrade gnu virtual private ethernet and
kill it (which should free the tun interface it uses). Following ifconfig
-a or other interface-related calls hang till the machine is rebooted hard
(shutdown hangs for obvious reasons).
