Can you test the following kernels, since this issue only happens with 3.9.0-1 and onwards:
v3.9-rc8: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc8-raring/ v3.9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/ v3.9.1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9.1-saucy/ You don't have to test every kernel, just up until the kernel that first has this bug. We need to identify the first kernel that has the bug and the last kernel that did not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181315 Title: unregister_netdevice: waiting for lo to become free.
