I also have no idea if we're actually fixing a symptom instead of a
real unrelated problem. What I know is that when I first reported this
problem last year, Alan Cox told me he had received reports of such
problems before, so this affects other Poulsbo users at least.


But I can't know for sure that it's related to hardware or the driver.



Either way, this patch can't make harm as far as I can see, but I
cannot test it as I don't have the required hardware.


I'll be Submitting the updated patch set.
