wifi freezing (module mwifiex)

[Julien Cubizolles <j.cubizolles@free.fr>]

I'm running vanilla kernel 4.2.0-rc3 on a Microsoft Surface Pro. The
wifi (module mwifiex) freezes the whole system after a few seconds of
use. The problem appeared around kernel 3.19.

I've tried to get some debug info with the dynamic debugging method,
using the following:

--8<---------------cut here---------------start------------->8---
echo "module mwifiex +p" > /sys/kernel/debug/dynamic_debug/control
echo "module mwifiex_sdio +p" > /sys/kernel/debug/dynamic_debug/control
echo "module mwifiex_pcie +p" > /sys/kernel/debug/dynamic_debug/control
echo "module mwifiex_usb +p" > /sys/kernel/debug/dynamic_debug/control
--8<---------------cut here---------------end--------------->8---

and getting the messages with

--8<---------------cut here---------------start------------->8---
while true; do dmesg -c >> mwifiex_logs.txt; sleep 1; done &
--8<---------------cut here---------------end--------------->8---

until the system freezes.

Surprisingly, there are very few messages related to mwifiex (see the
following logs). Is there something wrong with the dynamic debugging ?
What other information could I provide ?

Julien.
