Hi Smitha, first of: please try changing the MAC of the adapter, not of the virtual interface (btw: are you sure, that you really intend to have a physical and a virtual interface that have the same configurations and the same metric?). second: guess your copy+pasted log shows: that you conca

Hi, first of all: have you tried doing a standalone memory test application? From what I see you are using either a Virtex-4FX or Virtex-5FXT device, correct? So I'd highly recommend doing a standalone test prior to booting Linux to verify the memory controller timings of the FPGA based SoC.
