ACEMAX Kiii hotspot function causes tvbox crashed

[gabrilies]

The ACEMAX Kiii tvbox has a BUG, it will always cause the tvbox crashed.

Connecting the tvbox to Internet by Ethernet port, and enable portable hotspot function. While someone is downloading something via this portable hotspot function, any other network activity on tvbox itself will cause the tvbox crashed (e.g.: watching online tv, wget something ). That means the portable hotspot function cannot work simultaneously with the tvbox itself.

It is identified as kernel panic:

The similar bug was found in similar s905 tvbox minix U1, however the minix had released firmware to fix this issue, will ACEMAX fix this issue ?
