Marcel,

With 2.6.1 out, I did some further investigation of the oops when
establishing PPP connection.  First of all, apparently oops happens on
7th attempt, after 6 successful sessions.  Next, I selected console VGA
mode with smaller font, and got the full Oops dump:

http://www.average.org/btoops/

(first picture is vanilla 2.6.1, second is 2.6.1-mh1)

As far as I can tell from analyzing the dump, and objdump of l2cap.o
object, BUG() happens when "sk_set_owner(sk, THIS_MODULE);" in
net/bluetooth/l2cap.c line 353 encounters zero refcount of the module. 
So, probably somebody incorrectly decreases the l2cap's refcount
elsewhere...

Any ideas on that?

Eugene
