Subject: unregister_netdevice: waiting for tap24 to become free
Date: Tue, 12 Jul 2005 07:12:07 +1200	[thread overview]
Message-ID: <42D2C487.60302@rimuhosting.com> (raw)
In-Reply-To: <20050709120703.C2175@flint.arm.linux.org.uk>

Hi.  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
