I'll submit one once I get everything else working on this board that I
need....  :-)

Hi Mike,

I had the same "hang" experience.  The file arch/ppc/platforms/pq2ads.c
contains the following function:

  void __init
   m82xx_board_setup(void)
  {
         /* Enable the 2nd UART port */
         *(volatile uint *)(BCSR_ADDR + 4) &= ~BCSR1_RS232_EN2;
  }



I had to ifdef-out the assignment statement above.  It appears that the
 definition for BCSR_ADDR in the kernel code differs from what U-Boot 
is
 using, and that area of memory isn't properly mapped into the kernel
 address space this early in the boot sequence.  As a result, I was
 getting an Oops() before the console was even enabled (I could see the
 Oops message by examining the kernel's printk log buffer using a
 BDI-2000 hardware debugger).




Good luck,
