Your command line looks wrong, because you forgot –icount, but specified other replay options.
I tried recording and replaying with your command line and the execution hangs at some moment of replay. The problem may be hidden in –dtb option, because it may add the devices without configuring replay for them. Can you specify the whole hardware configuration in the command line?

I'm a bit stuck to get the drive part right, e.g.: -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 \ fails with: qemu-system-arm: -device scsi-hd,drive=img-blkreplay: Conflicts with use by img-direct as 'root', which does not allow 'write' on #block968
