I just wanted to ask if there is any progress on this issue since I haven't
heard anything for a month. Please let me know if you need any additional
information.

I've no idea if there's any progress.  Meanwhile I've an easy way of
testing of my brcm4313 card in a mini-itx board with mini-PCIe slot.
It works rather nicely and the stalls are easy to trigger.
Running 3.16 kernel right now, tried to d/load a file from the
AP, -- boom, it stalled after 77Kb.

Since the previous discussion apparently ended prematurely and no patches
to try emerged, I don't have anything to try on it...

In our last email exchange I got the impression you switch to Intel 
board and did not want to keep replacing cards for testing. Nice to hear 
you have an alternative setup for this and I assume are willing to do 
some testing.

I submitted two patches upstream and additionally I have attached two 
other that are still under review. Could you try these patches and sent 
me the content of the two debugfs files 'macstat' and 'hardware' after a 
stall has occurred.
