Hi,

I am a newbie at the linux kernel.I am trying to boot an ECG machine using Linux kernel 2.6.36 which has an alchemy architecture on a Db1200 board.The machine is getting booted properly when using Linux kernel 2.6.33.2 through both flash & nfs. Since we have ournown smc911x-regs board we have also included the structure for this in platform.c of Db1200 board.
I am getting stuck at the following step:

After this the machine always keeps on resetting. Please let me know what to do ASAP.
