I I think grub isn't seeing my updated changes when I'm setting up
kdump on F-20.
First I installed the the packages kexec-tools, crash,
and kernel-debuginfo.
Next I added crashkernel=128M
to GRUB_CMDLINE_LINUX
the in /etc/default/grub.
Then I rebuild the grub config with:
grub2-mkconfig -o
/boot/grub2/grub.cfg and it creates the file ok.
But, after rebooting, kdump hasn't started and I get the error from
systemctl status kdump:
kdump.service - Crash

kernel arming.
May 26 19:15:03 tesla systemd[1]: Unit kdump.service entered

Which leads me to think that my grub.conf really isn't working for
some reason.
This is on an AMD system with 16 Gigs of ram, so available memory is
definitely not a problem.
Could be something else, but in any case I'm sure I'm missing
something stupid ...
Thanks.
