Comment 1 John W. Linville 2011-07-12 19:54:29 UTC 
How often does this happen?  The trigger for the warning looks like it should be rather rare.  Of course, it should also be rather harmless -- so maybe we shouldn't bother warning about it either...
Comment 2 Misha Shnurapet 2011-07-13 01:59:27 UTC 
It's always reproducible.

I can't agree it's harmless because it is followed (or preceded) by a crash of the kernel, also no connection can be established.
Comment 3 Misha Shnurapet 2011-07-13 03:51:16 UTC 
I'll explain. I replaced the old BCM4312 card on my Dell mini 1011 (10v) with AR9280 and trying to use it normally. What I do when I get this is trying to connect to my home wifi network protected by a 63 or 64-character WPA2 passphrase. Upon this, Linux crashes and this warning is caught by ABRT.

*** Bug 716585 has been marked as a duplicate of this bug. ***
Comment 5 John W. Linville 2011-07-13 15:05:24 UTC 
Luis, do you have any idea why this TSF read would timeout?  If not, can you convince some of your Atheros brethren to take a look at this and add themselves to the Cc list? :-)
Comment 6 John W. Linville 2011-08-24 15:39:48 UTC 
Does this problem persist with 2.6.40 (or later) kernels?
Comment 7 John W. Linville 2012-01-09 19:17:05 UTC 
Closing due to lack of response...
