Greetings, I hope someone can help with this.

I am running the RHEL 7.4 debug kernel:

uname -r

3.10.0-693.21.1.el7.x86_64.debug

A kernel vmcore has been created while debugging an issue and is in /var/crash/ as per usual. However, when I attempt to do crash analysis I get this:

crash /var/crash/127.0.0.1-2018-04-10-12:16:08/vmcore /usr/lib/debug/lib/modules/3.10.0-693.21.1.el7.x86_64/vmlinux

stuf...

And then:

crash: /usr/lib/debug/lib/modules/3.10.0-693.21.1.el7.x86_64/vmlinux and /var/crash/127.0.0.1-2018-04-10-12:16:08/vmcore do not match!

But I cannot find out how to install the appropriate vmlinux for the debug kernel which I presume would be in /usr/lib/debug/lib/modules/3.10.0-693.21.1.el7.x86_64.debug/vmlinux but that file does not exist despite installing every kernel-debug-devel file and debuginfo-install file I could find.

Does anyone know where I can get the right debug kernel vmlinux file?

Thanks,

• Greg
