Hi Thomas How many different boards have you tried? I've not had problems with the board i have. Using the plathome supplied kernel, i've rebuilt the kernel, which is a good memory test. Using mainline, i've booted a number of times when developing the thermal driver and not had problems. I would hate to disable 2GB of RAM just because your board has a fault. Andrew
