Most real machines in core set MACHINE_EXTRA_RRECOMMENDS = "kernel-modules" which means that all images including initrd have all kernel modules by default. Only default qemu machines don't do this and instead the kernel configs there seem to include enough drivers built-in to mount the rootfs, and this may be reflected in qemu machine configuration e.g. which block device emulation is used. Since for initrd "boot to rootfs" usecase full set of kernel modules way too much, use the subset from kernel-initrd-modules which should work on all machines. If not, then the KERNEL_INITRD_MODULES_REGEX needs to be fixed for the machine or for everyone to include any missing driver classes. Same could be achieved by introducing a MACHINE_EXTRA_INITRD or similar variable for machine configs to define extra packages for initrd usecase of mounting target rootfs. I have not done this for now since currently only user is kernel-initrd-modules. Installing kernel-initrd-modules by default enables the machine specific kernel configs to move drivers from built-in to modules. The other e.g. firmware packages installed via MACHINE_EXTRA variables in core machines are not needed to mount the rootfs.
