Actually, I think it's the rfkill support (or lack thereof) that's causing you
trouble.  But we're looking at that as well.

The outstanding reported issues that I'm aware of are:
	- 43224 crashes
	- missing rfkill support
	- suspend/resume problems
	- 4313 infinite loop in some cases

In terms of process, should these all get filed in bugzilla.kernel.org (or
somewhere else), or just track them via email and our TODO list?

Thanks,
