OK!

Hunk #1 .. #3 are already included in the kernel sources. And the other
parts of the patch did fix the Oops.

Now I get only (with 2.6.18):

acer01:~$ ircp -r
Waiting for incoming connection
srv_obex_event(): Link error

and in /var/log/kern.log:

Oct 29 21:35:59 localhost kernel: irlap_change_speed(), setting speed to
115200
Oct 29 21:35:59 localhost kernel: irlmp_state_dtr(), Unknown event
