This is caused by the VFS library Hakefile not listing ahci_port as a
Of course, why should it? The problem is that to access an AHCI device,
you need ahci_util.h, which is a public header file (it's in /include)
but nevertheless includes a device header (which really should be private).
The reason we didn't catch this is that, will parallel builds, sometimes
dependencies for /usr/ahcid would be built first, which would cause the
missing file to be generated.
More generally, moving forward, we should really have ahci encapsulated
as a block/bulk transport driver in /usr/drivers, and not have any
dependencies on it in the VFS library.
The quick fix is to add ahci_port (and probably ahci_hba) to the
Mackerel dependencies for VFS.
A better approach is to prevent ahci_util.h from including
