** Description changed: After upgrading from linux 3.2.0-24.39 to 3.2.0-25.40, my computer will no longer shut down after using a VirtualBox virtual machine. The following is printed every 10 seconds when it tries to unload the VirtualBox networking modules: - unregister_netdevice: waiting for vboxnet0 to become free. Usage + unregister_netdevice: waiting for vboxnet0 to become free. Usage count = -1 To shut down, I have to hold down on the power button for 5 seconds to power off. This bug has been reported to VirtualBox. A fix for their network driver has been committed to their svn repository, but a release with the fix is not yet available: - https://www.virtualbox.org/ticket/10624 - https://www.virtualbox.org/changeset/41548/vbox + https://www.virtualbox.org/ticket/10624 + https://www.virtualbox.org/changeset/41548/vbox It looks like the culprit is the kernel changes to net/dev/core.c between 3.2.16 and 3.2.18. I'm guessing this is a bug in VirtualBox that was only exposed when the kernel code changed, but it might be a bug in the kernel that the VirtualBox devs had to work around. Either way, I'm guessing lots of people will experience this issue if the new kernel hits -updates. - --- + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
