Please install tuxmake and run attached script to reproduce reported issues,
$ pip3 install tuxmake
$ ./memfd-crash-test-qemu-i386.sh

This script downloads kernel Image and rootfs and runs run_hugetlbfs_test.sh.
If you have any questions please get back to me.
For your reference I have attached logs.txt
