I am also experiencing this bug. This issue did not occur on precise, however it does occur on trusty. I have not tried non-LTS releases.
I can confirm that the same issue occurs on the current upstream mainline kernel. I have reproduced the issue with 3.17.1-031701-generic ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358226 Title: kernel and lockd xprt_adjust_timeout rq_timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
