[Kernel-packages] [Bug 1403152] Re: unregister_netdevice: waiting for lo to become free. Usage count
@ddstreet, the Ubuntu-lts-3.19.0-49.55_14.04.1 doesn't seem to fix this issue. We just upgraded a Juno openstack environment to this kernel version and we are still seeing this on a network node.

[Test Case] Setup multiple containers in parallel to mount and NFS share, create some traffic and shutdown. Eventually you will see the kernel message.

[Kernel-packages] [Bug 1272765] Re: Xbox 360 wireless controller light continues blinking after sync with receiver
I am experiencing the same issue, my setup is: - ubuntu 14.04 - kernel 3.17 - wireles xbox controller A work around will be nice. -- 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/1272765 Title: Xbox 360 wireless controller light continues blinking after sync with receiver Status in linux package in Ubuntu: Triaged Bug description: I'm trying to use an Xbox 360 wireless gamepad with Ubuntu 13.10 64-bit (I've confirmed that this bug affects 14.04 as well). For background, the 360 wireless controller uses a receiver (also made by Microsoft) that plugs into a PC via USB. The controller syncs with the receiver by pressing a button on both. The "xpad" driver in the kernel seems to support most of its functionality just fine, but the light on the controller continues flashing forever after syncing with the receiver. Having a constant blinking light on one's controller is annoying and makes the user experience feel sloppy. As best I can tell, the version of the xpad driver in the mainline kernel hasn't been touched in a few years. Valve, creators of Steam and SteamOS, have done work on the driver recently and have fixed this bug. (Ubuntu PPA for this driver here: https://launchpad.net/~mdeslaur/+archive/steamos ) It would be really nice if 14.04 and all future versions of Ubuntu could use Valve's version of this driver, as it's the version being actively maintained. Without it, gamers trying out Ubuntu will get a low impression of Ubuntu's polish and support for gaming. --- ApportVersion: 2.12.5-0ubuntu2.2 Architecture: amd64 AudioDevicesInUse: USERPID ACCESS COMMAND /dev/snd/controlC2: jpl2694 F pulseaudio /dev/snd/controlC1: jpl2694 F pulseaudio /dev/snd/controlC0: jpl2694 F pulseaudio DistroRelease: Ubuntu 13.10 HibernationDevice: RESUME=UUID=d1b7d2f8-4929-4b69-8cc9-ecaa3857fa09 InstallationDate: Installed on 2013-04-28 (272 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) IwConfig: eth0 no wireless extensions. lono wireless extensions.

The problem has been present since upgrade to Utopic, but have recently become worse, maybe because of error message [drm:intel_dp_start_link_train] *ERROR* too many full retries, give up which appears in all terminals.
