Hi,
Got a bug report:
https://bugzilla.gnome.org/show_bug.cgi?id=644551
that has this error log in it. Is that enough to figure out where
things have gone wrong in the firmware?

It appears like the configuration that gets sent to wpa_supplicant is
TKIP + WPA2 which seems kinda wrong, doesn't WPA2/RSN require CCMP?

IIRC, it's quite hard for 3945. But I might be wrong. What's the kernel
version here?

That seems fine. WPA2 certification requires the ability to do CCMP I
think, but RSN can also be set up to use TKIP, say if you set up
WPA/WPA2 on the network. WPA is just a pre-RSN (WPA2) method of
advertising pretty much the same thing.

We have information that disable_hw_scan=1 workaround that problem.
That would be second reason to use software scanning by default,
first was very bad performance on some configurations. I'm going
to post a patch, which change that option on iwl3945.
