[Bug 976288] Re: Bluetooth adapter fails to work after resume

[steveG]

I'm having this bug now as well since a couple of weeks. Had it just resulting in a kernel panic a view minutes ago on my fully updated 12.04 running 3.2.0-25-generic. Moreover I've seen it before in 3.2.0-24-generic. 

Below the end of kern.log at the latest panic on 3.2.0-25:
