Aha. That was going to be my next area to ask about.
I would swear this files were deployed in OE in the past.
I apologize for the noise in the list!
I'm glad it has worked out!

Problably the issue about modules.builtin was a nosense, becasuse
patching the kernel Makefile in order to include this file dosen't fix
the problem.
That said, I am unable to make work properly the /lib/modules folder.
The problem is the "make modules_install" is not putting all the files
in the target folder (I mean the modules.dep files an so on). This is
the log output when the task do_install of the kernel.bbclass:

The make modules_install uses the target folder INSTALL_MOD_PATH in
order to install the modules, however you can see only the files
"modules.builtin" and "modules.order" are properly installed. The
"make modules_install" work fine if I run this command from a
"devshell", however from the "bitbake virtual/kernel -c install" is
not properly working.
Can anybody give me a hint?
Many thanks.

Hi!
I've found a possible issue with the depmodwrapper (in image.bbclass
-> do_rootfs) and the old kernel tree 2.6.32.
The final rootfs image is not properly populated with the necessary
kernel module files for the module-init-tools utility:
/lib/modules/<kernel-version/
modules.alias
modules.alias.bin
modules.builtin
modules.builtin.bin
modules.dep
modules.dep.bin
modules.devname
modules.order
modules.softdep
modules.symbols
modules.symbols.bin
This tool depmodwrapper is using the kernel Makefile generated file
"modules.builtin", this file is not generated by the kbuild kernel
system in the 2.6.32 kernel. This feature was included in the 2.6.33
branch [1].
So the image.bbclass is broken for kernel trees below 2.6.33 version.
However the bitbake.conf shows the variable OLDEST_KERNEL = "2.6.16".
Many thanks!
