Hi all,

Kernel : Linux-2.6.29
Arch: Powerpc (ppc44x)
Target: Xilinx ML507 Virtex5

I have an issue in "Reset System" of Xilinx ML507 target board. I am using
Compact Flash to boot the target ( using system ACE file to boot the
target), during the process reset or reboot command on the target, I am not
able to reboot the target completely, here is the snapshot:

---------------------------------------------------------------------------------------------------
