Hi,
I'm using 4.1 stock kernel on imx cpu and 8897 wifi chip connected
over pcie to cpu. I did stress test by disabling AP in loop when wifi
card is connected to perform scanning and reconnect. After 25 attempts
I'll get following and after that wifi is unusable:

I did look to some new patches and found following patch [0] but it
didn't help. Is there anything else I can try to fix this issue?
Thanks a lot.
