(apologies for double post, I accidentally pressed "post" before finishing)

I have a similar issue on a Dell XPS 13. Bluetooth does not work after suspend, it started happening after upgrade to 13.10.

In my case the workaround is to disable wireless using the hardware switch (Fn+F2), then turn it back on.
(the similar network-manager workaround reported by the bug opener does not work for me)
