The command I tried was:

time ./buildroot/output.arm~/host/usr/bin/qemu-system-arm -M versatilepb
-append 'root=/dev/sda nokaslr norandmaps printk.devkmsg=on printk.time=y -
lkmc_eval="/rand_check.out;wget -S google.com;/poweroff.out;"' -kernel
./buildroot/output.arm~/images/zImage -dtb
./buildroot/output.arm~/images/versatile-pb.dtb -nographic -drive
file=./buildroot/output.arm~/images/rootfs.ext2,if=scsi,id=img-direct,format=raw
-drive driver=blkreplay,if=none,image=img-direct,id=img-blkreplay -device
scsi-hd,drive=img-blkreplay -netdev user,id=net1 -device
rtl8139,netdev=net1 -object filter-replay,id=replay,netdev=net1

and the required files can be downloaded from:

https://github.com/cirosantilli/linux-kernel-module-cheat/releases/download/test-replay-arm/images.zip

They were generated with:

./build -a arm

on that repo.
