Comment 156 for bug 1730924

Created attachment 290067
mwifiex crash log on SB1 with ps_on, 5GHzAP

- power_save on
- connected to 5GHz AP
- connection instability (ping not responding)
- firmware crashing eventually

Journal log and devcoredump are included in the archive. I kept sending ping to 192.168.1.1 and the output was redirected to kmsg to show connection stability
state.

    $ ping 192.168.1.1 | sudo tee /dev/kmsg
