This crash is currently critical when using traffic control (tc) in one of the Ubuntu LTS releases, bionic and xenial linux-hwe.
I referred to a simple script in the debian bug tracking system that triggers the kernel crash. In my case a normal shutdown/reboot triggers the crash, when the kernel tries to perform cleanup for tc. This leaves the system hanging in a crashed state. In the debian bug reporting system this bug had severity critical and it was fixed March 12th 2019. Is there anything that can be done in order to get this fixed for Ubuntu LTS (bionic and xenial linux-hwe) during the SRU cycle 13-May through 02-June ? -- 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/1825942 Title: kernel crash : net_sched race condition in tcindex_destroy() Status in linux package in Ubuntu: Confirmed Bug description: I am running into a kernel crash issue using latest Ubuntu 4.15 kernel.
