[Dextrose] Problems compiling bluetooth module

[Emiliano Pastorino]

Hi, it's me again with new problems.

I'm trying to compile the bluetooth modules again, but now I've new issues.
When I try to insmod any module, I get the same error:

insmod: error inserting 'net/bluetooth/bluetooth.ko': -1 Invalid module
format

I'm working on an XO-1 with a Dextrose based build, using kernel 2.6.31.
uname -r shows this:

2.6.31_xo1-20100701.1605.1.olpc.a8f1b26

and rpm -qa | grep kernel this:

kernel-firmware-2.6.31_xo1-20100701.1605.1.olpc.a8f1b26.i586
kernel-devel-2.6.31_xo1-20100701.1605.1.olpc.a8f1b26.i586
kernel-2.6.31_xo1-20100701.1605.1.olpc.a8f1b26.i586
kernel-headers-2.6.31_xo1-20100701.1605.1.olpc.a8f1b26.i586

I've downloaded kernel-2.6.31_xo1-20100701.1605.1.olpc.a8f1b26.src.rpm
from http://dev.laptop.org/~kernels/olpc-2.6.31-xo1/ and installed it.

The steps I followed were the same as with the 2.6.25 kernel, with little
modifications since now there's a configuration for XO-1.5 also:

make ARCH=i386 INSTALL_MOD_STRIP=1* xo_1_defconfig*
make ARCH=i386 INSTALL_MOD_STRIP=1 menuconfig
there, I activated bluetooth
make ARCH=i386 INSTALL_MOD_STRIP=1 M=net/bluetooth

Then, when i execute "insmod net/bluetooth/bluetooth.ko", I get:
insmod: error inserting 'net/bluetooth/bluetooth.ko': -1 Invalid module
format

modinfo net/bluetooth/bluetooth.ko shows:

filename:       net/bluetooth/bluetooth.ko
alias:          net-pf-31
license:        GPL
version:        2.15
description:    Bluetooth Core ver 2.15
author:         Marcel Holtmann <marcel at holtmann.org>
srcversion:     934DDFF641FDE73DF4A50F3
depends:
vermagic:       2.6.31.6 preempt mod_unload modversions GEODE 4KSTACKS

so bluetooth.ko can't be just garbage.

I'm getting the same behaviour with all the other modules from net/bluetooth
and drivers/bluetooth.

Any clues?

Thanks
