Thanks.  Please specify a version number next time.

Interesting.  I'd never seen this message before, but a search of
the linux-wireless yielded some hits.

No great ideas from me.  So:

 - please boot without the virtualbox drivers to rule them out as
   a cause

 - does unloading the acer_wmi driver help?  (I wouldn't expect it
   to, but it seems worth a check.)

 - is "rfkill list" output as expected?

 - you mentioned that with some earlier 3.2.y kernel you had similar
   problems, though there was a workaround.  May I assume that
   earlier kernels worked fine?  Of the kernels listed at
   <http://snapshot.debian.org/package/linux-2.6/>, which is the
   newest version that works without problems?

 - please file a separate bug for the laptop with different hardware.

 - does this always happen right away or only in some circumstances?
   (e.g., after a suspend/resume)

 - can you reproduce this without using wicd?  i.e.

	install iw and iproute
	stop wicd
	ip link set wlan0 up
	iw dev wlan0 connect -w <SSID> key d:0:<WEP key>
	dhclient wlan0

   with

	iw event -t

   running in another terminal to see if anything interesting happens.

Vaguely reminiscent of https://bugzilla.kernel.org/show_bug.cgi?id=16436
but that bug has a different regression range which makes it not a great
match.  So I look forward to some clues to narrow this down.

Hope that helps,
Jonathan
