Hi
there is some problems on ethernet controller.
My board use lan8720a and it do not support dynamic control ethernent clock well. So i let it normal on. And it solve the problem on kernel support by freescale.But it failed on uc 16.
The ethernet port seem well but kernel freeze at here:

[ 3.480172] usbcore: registered new interface driver quatech2

if i use only one ethernet port it’s run well.
the kernel is here.
the drivers seem no different from freescale’s kernel.
and i change the driver at /drivers/net/ethernet/freescale/fec_main.c
Do someone have some idea about this problem?Thanks.
