Subject: 3.4-rc2, ilwagn still most of the time completely unusable

Dear all,

I am now having problems with the iwlagn driver since about 4 kernel
revisions, without any tendency that things are getting better.

I already have reported that with 3.3-wl there are hundreds and thousands
of lines
	delba from 00:0a:79:eb:56:10 (initiator) tid 0 reason code 39
	Rx BA session stop requested for ...
*IF* it is connected.

On the contrary, it sometimes not even connects, after reloading the module,
retrying many times, today my log was smarmed with messages:
	[ 9457.156030] wlan0: authentication with 00:24:c4:ab:bd:e0 timed out
	[ 9457.176828] iwlwifi 0000:06:00.0: ACTIVATE a non DRIVER active station id 0 addr 00:24:c4:ab:bd:e0

Above is all on the University network, which is rather new and
in good shape.

But I want to report *SOME* progress: Formerly I had *BIG* problems 
with my home network (some strange Corega WL router AFAIR, Japanese only,
but it was working without a click before 2.6.38 or 39 or so).
Now, when I *DISABLE* 11n (11n_disable=1) then all the problems are
gone *AT*HOME*, no warnings anymore, no complains, no hickups.
On the university it is still a pain.

As I have already sent debug output etc etc as requested here, I will
not repeat that unless asked for it.

Well, hope that in another 20 kernel revisions that might get fixed,
we are not talking about a brand new wlan adapter anymore ... that
was some years ago ... especially the regression from 2.6.38 where it
was working without any problem to the current very sad state of affair
is frustrating.
