Not really, this was the second case I encountered it in a very long time. My guess is that it could be reproduced in reasonable time with moderate network traffic and a bunch of lxc-start/stop. After a while it should happen.
Anyway reading the commit message it's very probable, that this commit will fix this issue. -- 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/1278591 Title: kernel hard lock on lxc-stop Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: Confirmed Status in “linux” source package in Trusty: Confirmed Bug description: Server crashed during lxc-stop.
