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
