Kernel starts and crashes with "unable to handle kernel paging request @

After turning debug on in some files I can see that the initrd memory
gets reserved and the dtb is parsed correctly.
PCI memory/io spaces are set up fine.
At first I thought this is a problem with the device tree since the call
trace always points to "of_"-functions and "strcmp".
Could you provide this call trace?

Scott,
after building a debug kernel and attaching the bdi2000 it looks like
the crash occurs during "console_init()" ...
Since we're using a dtb I omit the "console=..." argument for the
kernel. Is this correct ?
If "console=/dev/ttyS0,115200N8" argument is given the serial console
stops working after console_init....
On other PowerPC system I could see something like this during boot :
-> find_legacy_serial_port()
stdout is /[EMAIL PROTECTED]/[EMAIL PROTECTED]
legacy_serial_console = 1
default console speed = 115340
<- find_legacy_serial_port()
Should I see this message also ?
Have I misconfigured anything ?
u-boot prints the following dtb :
