Subject: kernel hangs


Hi,

         I have compiled linux-2.6.25 for MPC837X processor and generated "vmlinux.bin" image and then
          integrated this image with "rootfs" to generate "uSystem".(This is done using mkimage utility)
         Then downloaded this uSystem image in flash and tried to boot linux from u-boot. but linux hangs  at
         "Transferring control to Linux (at address 00000000)"
         .....please refer log below.

         If you have any idea due to what this problem may occur, please help me.
