linux-backports-modules-wwan-lucid-generic modules are compiled against server kernel and not loading on generic

[Jan Alsenz]

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

# modprobe usb_wwan

dmesg:

# uname -a
Linux nb-ja 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:46 UTC 2011 x86_64 GNU/Linux

It would be great if someone could fix this.

I am having a similar problem. Similar setup as above, hardware Lenovo ThinkPad X201 which worked fine before. It would be great to get it working again.
