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.

You didn't tell which kernel it is based on.  So I tried it on 3.16,

Ok, I misunderstood you apparently, -- I only tried 2 patches,
while I should try all 4.  So here it goes.

The hardware info again:

As far as I can see, the stats are never updated during stall,
no numbers are changing, at least while the download is waiting
for the next packet.  Sometimes wpa_supplicant does something
little, so some stats gets updated, eg, this is how it looks like
after about 2..3 minutes:

This is with 3.18-tobe kernel (current Linus git).

Dunno if this is helpful or not...

Well, it shows tx looks ok, but with download there is not much of that
going on. At least no large packets. However, I did find some missing
pieces related to bt-coex. Given that you device is a wifi-bt combo card
that is likely an issue for you. One of the missing pieces looks in
sprom for parameters and that is provided by bcma. However, it does not
seem to extract bt-coex related stuff. So I have attached a patch based
on 3.18-rc5 for bcma that dumps the sprom contents. Could you sent that
content to me.

Arend
