Date: Tue, 31 Jul 2012 16:11:18 +0200 From: Bernard Pidoux <bernard.pidoux@...e.fr> To: linux-hams <linux-hams@...r.kernel.org>, Linux Netdev List <netdev@...r.kernel.org> Subject: CPU: 0 Not tainted (3.1.9+ #1) when ifconfig rose0 down Hi, I observe systematically a kernel panic when I try to shutdown rose0 device using ifconfig rose0 down This is happening on two very different ROSE implementation, one is on a machine with x86-64 kernel 4.6.3 on an Intel core 2 duo CPU the other is on a RaspBerry Pi with Raspbian and 3.1.9+ wheezy kernel recompiled with AX.25 modules (ax25, rose, netrom, 6pack, kiss) enabled. Here is an image of the screen dump : http://f6bvp.org/photos/rose_device_event.JPG It can be noticed that PC is at rose_device_event and LR is at sock_def_wakeup One thing to be noticed is that when I close before all ROSE and AX.25 applications, there are still a few populated sockets, probably for one of the program did not close the sockets properly. I that case, does rose module should accept to shutdown rose0 device ? However, I guess that it should not create a kernel panic due to a kernel NULL pointer. I don't know what to do in order to debug that issue.
