[Kernel-packages] [Bug 1874266] Re: Intensive NFS operations could lock whole system
Of course all apport information were collected prior to hangup. After hangup running new processes is almost impossible (if it requires performing some IO operations, and almost always it does). ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1874266 Title: Intensive NFS operations could lock whole system Status in linux package in Ubuntu: Confirmed Bug description: After last update from kernel version 4.4.0-176-generic to 4.4.0-177-generic my machine which does repository mirrors on NFS filesystem hung.
