Stefan Bader was able to reproduce this kernel oops using the server ISO. John Johansen was pretty sure the oops was related to Apparmor. Merging the latest Apparmor fixes that were coincidentally staged for the next upload appears to have corrected the problem. My testing has had positive results. Look for these fixes in linux 4.4.0-9.24. ** Changed in: linux (Ubuntu Xenial) Status: Triaged => In Progress ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => Tim Gardner (timg-tpi) -- 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/1550755 Title: Reliably crash kernel 4.4.0.8-generic by reinstalling all packages and waiting for bind9 Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: Hiya I periodically do a full reinstall of all packages just to see what breaks.

[Kernel-packages] [Bug 1550755] Re: Reliably crash kernel 4.4.0.8-generic by reinstalling all packages and waiting for bind9
apport information ** Tags added: apport-collected xenial ** Description changed: Hiya I periodically do a full reinstall of all packages just to see what breaks. Today it's the kernel :) Oddly I have reproduced this on several machines. Simply fire up aptitude, go to "Installed" packages, hit Shift-L to reinstall, then g and g again to kick it off.
