PPC440GP board hangs

[Denny]

Hi, 
   After success uncompress the kernel to ram, it hangs,
## Transferring control to Linux (at address 0000000)
 
   Does anyone encounter the symton on PPC440GP? I double checked my external UART clock and system clock both in hareware and software, they are all right.
 
the log buffer is as below:
