Public bug reported:
At least for versions 2.6.32-29.28 and 2.6.32-30.29 the modules can not
be loaded by the generic kernel.
I just noticed that my WWAN connection was not working and investigated
a bit. It seems, that the modules have been compiled against the server
kernel:
# modinfo usb_wwan
filename: /lib/modules/2.6.32-30-generic/updates/wwan/usb_wwan.ko
license: GPL
version: v0.7.2

depends: usbserial
vermagic: 2.6.32-30-server SMP mod_unload modversions

# modprobe usb_wwan
FATAL: Error inserting usb_wwan
(/lib/modules/2.6.32-30-generic/updates/wwan/usb_wwan.ko): Invalid module format
dmesg:

# uname -a

GNU/Linux
It would be great if someone could fix this.
