I have installed kmod-devel, still the configure error occured. But it
worked for me with the epel repo you provided to install ndctl.
Seems it can't be reproduced on my beaker machine with 18G memory. I did
steps as Jeff said, and reboot more than 5 times, no crash seen.
Below is the abstracted part of boot log.
