Users of kdump won't be able to dump if their system uses
hugepages/hugepagesz on the cmdline.
1) Install crashdump
2) Boot machine with hugepages= or hugepagesz= set to a significant amount of
3) Try to crash with 'echo 'c' | sudo tee /proc/sysrq-trigger'
If users really want to have hugepages/hugepagesz on the kexec'd kernel for
