hmm
Ok - I assume you mean this patch:
http://git.kernel.org/?p=linux/kernel/git/padovan/bluetooth-2.6.git;a=commitdiff;h=b7d850641d2bc45b2320bfcb096f11406890ff3a
It seems to be detaching timer slightly differently as the one from
Keith probably.
Here is the trace I've got with older Keith's patch (which I've
believed was fine already)

I'll see whether new version will not show this warning.

I pushed a patch that fixes this in a better way, it's on the bluetooth-2.6
tree (should arrive to linus tree in some days).

Yep - it looks like the patch
http://marc.info/?l=linux-bluetooth&m=130230770920378&w=2
