--- Comment #5 from cs_gon at yahoo.com ---
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 I tried a newer version of the crash tool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:

/usr/lib/debug/lib/modules/4.5.0/vmlinux dump.201603181202
