so I took the patch apart and actually found a few more issues. I am not
sure if they should be applied this late in -rc phase.

Rafael, can you pull from my tree and test the changes:

git://git.kernel.org/pub/scm/linux/kernel/git/holtmann/bluetooth-2.6.git

It would be interesting if these fixes are enough. Or if you need the
attached suspend/resume patch.

Regards

Marcel
