Well, that's impressive...

> ./vmlinux: (unknown)
> live system kernel: 4.4.3

That's a harmless warning, but what do these commands show:

$ strings vmlinux | grep "Linux version"

and

$ cat /proc/version

The gcc-related data in those two strings are being compared.

> crash: cannot open secondary temporary file

When do you see that message?

The System.map file is not necessary if the vmlinux is the kernel
that the live system is running.
