Hi, My borad consists of a rt5350 core module and a bottom board. The bottom board is layouted by my colleague. I buy rt5350 core module on taobao.com in china as follow:http://item.taobao.com/item.htm?spm=a230r.1.14.169.DH7HWh&id=35442287707 But I don't think you need to get a rt5350 board to look at this bug. The bug is in ralink-gdma.c, so youcan test it on your own board.
