kernel: unregister_netdevice: waiting for vboxnet1 ... => Fixed in SVN

[macachuto]

Story is here:  https://forums.virtualbox.org/viewtopic.php?f=7&t=49763&sid=d7faa7a4d50269fc72a18fbfda58a954

In short: When I shutdown system or execute: /etc/init.d/vboxdrv stop I got: kernel:[ 2157.199178] unregister_netdevice: waiting for vboxnet1 to become free. Usage count = -2

In dmesg also there is: dev_remove_pack: ffff8802100c10d8 not found.

Current vbox version: 4.1.16, but this problem started before. I thought it started when I updated kernel, because normally I do not update vbox often, but in bugzilla.redhat.com, where I opened bug about this problem, I got suggestion that this is problem with vbox, and I should write there.

So, please review my thread.

Which kernel did you use before? I'm not that certain that this is really a VirtualBox problem.

[macachuto]

This is history of my kernel updates:

May 06 09:54:27 Installed: kernel-3.3.4-1.fc16.x86_64 May 19 00:08:04 Installed: kernel-3.3.5-2.fc16.x86_64 May 26 11:33:03 Installed: kernel-3.3.6-3.fc16.x86_64 May 28 21:51:22 Installed: kernel-3.3.7-1.fc16.x86_64

I really do not remember since when I start to have this issue, but I had this with kernel-3.3.6-3.fc16.x86_64 and kernel-3.3.7-1.fc16.x86_64.

So it may starts from 3.3.5-2.

This is my bug for Fedora:  https://bugzilla.redhat.com/show_bug.cgi?id=825518

Starting with Linux kernel 3.2.18 notification handler gets called for all devices when this handler is being unregistered. This caused vboxnetflt to decrease twice the reference count of the device it was attached to.

I have the same problem. I cannot shutdown cleanly my machine anymore.

my machine is fedora 16 x86_64, latest kernel 3.3.7-1.fc16.x86_64.

kernel:[31089.065000] unregister_netdevice: waiting for vboxnet0 to become free. Usage count = -1

please attach patch so we can patch the 4.1.16 version until the next version is released.

Same problem in Ubuntu 12.04 with an upgrade to 3.2.0.25 Kernel version. Fixed with the use of previous kernel version.

Is r41548 the commit that fixed this in svn? The commit message for that commit says #6225, which appears unrealted.

[aleksey]

Yes, you are correct. r41548 contains the fix. 6225 is an internal tracking number and has no relation to the public bug tracker indeed.

Fix in VBox 4.1.18.

I have a similar problem with VirtualBox 4.3 on Ubuntu 13.10 64-bit (Linux 3.11.0-13-generic). On every reboot I see this message:

unregister_netdevice: warting for vboxnet0 to become free. usage_count = 1

[z0rn]

unregister_netdevice: warting for vboxnet0 to become free. usage_count = 1

Same problem here with Ubuntu 12.04 using kernel 3.11.6-031106-generic #201310181453 and VirtualBox 4.3.0.

Replying to szx:

I have a similar problem with VirtualBox 4.3 on Ubuntu 13.10 64-bit (Linux 3.11.0-13-generic). On every reboot I see this message:

unregister_netdevice: warting for vboxnet0 to become free. usage_count = 1

I also have exactly the same problem on Ubuntu 13.10 64-bit and latest VirtualBox. System configuration:

$ dpkg -l | grep virtualbox

This is handled in ticket #12264.
