There is a workaround:

$ sed -i 's/SKIP_INITRD=yes/#&/' test.sh
$ sudo make run KERNEL_BIN=/boot/vmlinuz-linux INITRD=/boot/initramfs-linux.img

[s-urbaniak]

Thanks a lot for helping out with this :-)

So, this the test.log of

$ cd systemd/test/TEST-13-NSPAWN-SMOKE
$ sudo make KERNEL_APPEND=debug KERNEL_BIN=/boot/vmlinuz-linux-userns INITRD=/boot/initramfs-linux-userns.img

is here: http://pastebin.com/5eGF9u4i

And the output of

$ lsinitcpio /boot/initramfs-linux-userns.img | grep modules

is here: http://pastebin.com/KER8qZ5Y

@s-urbaniak , thanks!

I don't see any ata_generic, pata_acpi, ata_piix or so

Does your mkinitcpio.conf contain HOOKS=.*block?

$ mkinitcpio --hookhelp block
==> Help for hook 'block':
This hook loads the necessary modules for most block devices using pata, sata,
scsi, firewire, usb, or mmc. Detection will take place at runtime. To minimize
the modules in the image, add the autodetect hook too.

I logged into QEMU:

hmm ... I guess it does:

$ cat /etc/mkinitcpio.conf
...
MODULES="vfat ext4 dm_mod dm_crypt aes_x86_64 i915"
...
HOOKS="base udev autodetect modconf block lvm2 encrypt filesystems keyboard fsck"
...

@s-urbaniak , what is the output of

ls /lib/modules/$(uname -r)/kernel/drivers/ata

How did you run mkinitcpio?

Try to remove autodetect and mkinitcpio -g no-autodect. Then make run INITRD=path-to-the-no-autodect

[lucab]

For reference, TEST-13-NSPAWN-SMOKE also fails on my debian (stretch) for a couple of reasons:

1. Missing FS drivers with SKIP_INITRD=yes (that is: CONFIG_EXT4_FS=m)
2. Funky initramfs scripts when picking it from the host (as my initrd does rootfs decryption, it has partitions config embedded into it)

I'm currently workarounding it with:

SKIP_INITRD=no
KERNEL_APPEND=cryptopts=source=/dev/null,keyscript=/bin/true,tries=1

[evverx]

Missing FS drivers with SKIP_INITRD=yes

Actually, we don't really need SKIP_INITRD=yes there.
I guess we can remove SKIP_INITRD=yes everywhere (note for me: TEST-08-ISSUE-2730 requires SKIP_INITRD=yes)

Funky initramfs scripts when picking it from the host

I'm not sure what to do about initramfs. Maybe, we should generate the "golden" initramfs and use it. But that's not so easy.

[evverx]

I can't remember what this issue is about and whether it has been fixed or not so I'll just close it.
