You should at least use a modern kernel for the best chance at getting this to 
work. The current version is something like 2.6.24 last time I looked, so 
2.6.15 is very old and possibly vulnerable to a number root exploits if not 
patched.

There's not enough info here for me to tell. Try running the daemons in debug 
in the forground (hcid, sdpd). Maybe run hcidump during the time you try as 
well.

-> Which patch i should add for upgrading my kernel.....?

Just download the latest kernel. Build, install.
