Cannot load lirc_serial on Ubuntu

[shacky <sha...@gm...>]

Hi.

I installed Lirc on my Ubuntu 7.10 system (gutsy unstable) and now I'm
trying to configure it.
I installed it following the guide at
https://help.ubuntu.com/community/Install_Lirc_Gutsy.
The installation of Lirc in Gutsy is now very simple and it installed
and configured without error.
But when I try to modprobe the lirc_serial module, I get this error:

kobject_add failed for lirc_serial.0 with -EEXIST, don't try to
register things whith the same name in the same directory.
kobject_shadow_add
kobject_set_name
device_add
platform_device_add
init_module
sys_init_module
prio_tree_insert
sysenter_past_esp

I'm using the "2.6.22-9-generic" kernel.

Could you help me, please?

Thank you very much!
Bye.
