Does anyone know the 'proper' way to enable a kernel module within LTSP
5.2.1?
Let me elaborate on the problem that has steadfastly put me into a
quasi-comatose state for the past week...
I have a piece of thinclient hardware (NorhTec MicroClient Jr DX -
eBox-3300MX) that utilises a Vortex86 SoC.
This particular SoC incorporates an "RDC Semiconductor, Inc. R6040 MAC
Controller" for ethernet functionality.
It seems the default LTSP client image that is built after invoking
'ltsp_build_client' excludes the required driver for the R6040 ethernet
controller, resulting in a "No interfaces found" error from the initrd when
trying to netboot LTSP. The required driver is available through
menuconfig, under 'Device Drivers--> Network Device Support --> Ethernet
(10 or 100Mbit) --> RDC R6040 Fast Ethernet Adapter Support'.
I have tried re-building a custom kernel within the CHROOT environment, and
I have tried building the module from source against the appropriate kernel
headers, to no avail. Upon netbooting LTSP with my custom built module, I
have received errors such as "r6040: no symbol version for module_layout"
which seem to indicate that, well, I haven't compiled the module correctly!
I cannot seem to get the 'versionmagic' string to be identical to that of
the rest of the modules already included in the LTSP initrd.
Hence, back to my first question. What is the proper way to add this module
to my current LTSP initrd? I would imagine the preferred way to do this is
to specify this in a .config file, so that when 'ltsp-build-client' is
called, is knows to include this particular module in the build. I've seen
all manner of things happening in:
/usr/share/ltsp/plugins/ltsp-build-client/
...but nothing that seems to allow including a previously-deselected module
in the kernel build process.
I can't count how many times I've rebuilt the LTSP initrd in the past week,
so please do add your wisdom to this thread!
Further information:
I am running LTSP on the following platform:
Linux 2.6.32-24-server #43-Ubuntu SMP Thu Sep 16 16:05:42 UTC 2010 x86_64
GNU/Linux
With the following version of LTSP installed:
ii ltsp-server 5.2.1-0ubuntu9
Basic LTSP server environment
The currently active LTSP kernel is:
2.6.32-29-generic
Thank you to all who have spared their time to listen to my incoherent
rambling. I hope you can make more sense of it than I can.
Best regards,
Tomas
