<pre>I rebuilt the 4.5.0 kernel from git, and tried to get more information/a better
stack trace with the crash tool, but sadly that didn't work.
Does anyone have an idea what to do? I tried a newer version of the crash tool
(7.1.4, from Xenial), but got the same result. Could a corrupted stack be the
reason for this?
Here is the output I got:
root@localhost:/var/crash/201603181202# crash
/usr/lib/debug/lib/modules/4.5.0/vmlinux dump.201603181202
crash 7.0.3
