Does it mean they gave me bad vmcore ? Why the version in "release" is
release: 3.10.0-693.17.1.el7.x86_64 ?

Subject: Redhat 5.11 dump
To: <crash-utility@xxxxxxxxxx>
Hi,
A production machine with Red Hat Enterprise Linux Server release 5.11
(Tikanga) kernel 2.6.18-431.el5 crashed.
I received vmcore, Since I dont have access to machine, and I need to
open the vmcore to analyze the dump, I have downloaded CentOS 5.11,
since centos 5.11 is EOL, I downloaded the 2.6.18-431.el5 kernel
manually, with debuginfo and debuginfo-common and installed them, so
far - seems ok.
I am trying to get call stack of the dump time, i get error:
[root@centos511test kernel]# crash vmcore
/usr/lib/debug/lib/modules/`uname -r`/vmlinux
crash 5.1.8-3.el5.centos
