Re: [Kernel-packages] [Bug 1403152] Re: unregister_netdevice: waiting for lo to become free. Usage count
Hey, here is a discussion about the reproducablity. I'm wrote very early in these thread that if I set the following network config in a container ip -6 tunnel add gt6nactr01 mode ip6gre local 2a4:4483:5:1709::2:1 remote 2a4:4494:f:997:217:110:59:5 ip link set mtu 1500 dev gt6nactr01 up ip addr add 2a04:4454:f:f003::1/64 dev gt6nactr01 ip addr add 169.254.193.1/30 dev gt6nactr01 it will hang on reboot, try it again just now an it works/halt! There is also a other possiblity to stop a lxc with the same result "waiting for lo to become free". And this is if you mount a nfs server with a lxc container, you have to change something apparmor but than it works perfectly until you try to reboot the lxc container. Is there any reason why not try to fix these reproducable problems first? cheers meno On Mon, Feb 9, 2015 at 6:50 PM, Rodrigo Vaz <1403...@bugs.launchpad.net> wrote: > I left a couple instances running with the mainline kernel > (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-rc7-vivid/) during > the weekend, it took more time to see the bug on the mainline kernel but > this morning one out of ten instances had the same problem so I'm > assuming mainline is also affected. > > Kernel version 3.19.0-031900rc7-generic > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1403152 > > Title: > unregister_netdevice: waiting for lo to become free.

[Kernel-packages] [Bug 1403152] Re: unregister_netdevice: waiting for lo to become free. Usage count
I try to make it reproducable and figured out that the problem is related to use of these kind of interfaces in a lxc container. The tunnel are working in the running lxc-container but if you stop or reboot the lxc-container the kernel reports this unregister_netdevice: waiting for lo to become free. here the ip link output in the container 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: ip6tnl0: mtu 1452 qdisc noop state DOWN mode DEFAULT group default link/tunnel6 :: brd :: 3: ip6gre0: mtu 1448 qdisc noop state DOWN mode DEFAULT group default link/gre6 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 brd 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 4: gt6nactr01: mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default link/gre6 2a:4:f:89:00:05:17:09:00:00:00:00:00:02:00:01 peer 2a:4:f:8:00:0f:09:97:02:17:01:10:00:59:00:05 or the command which creates this kind of tunnels ip -6 tunnel add gt6nactr01 mode ip6gre local 2a4:4483:5:1709::2:1 remote 2a4:4494:f:997:217:110:59:5 ip link set mtu 1500 dev gt6nactr01 up ip addr add 2a04:4454:f:f003::1/64 dev gt6nactr01 ip addr add 169.254.193.1/30 dev gt6nactr01 i attach a dmesg output and hope that you can reproduce the problem. thx meno ** Attachment added: "rt-01-ham.dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1403152/+attachment/4282311/+files/rt-01-ham.dmesg -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1403152 Title: unregister_netdevice: waiting for lo to become free.
