PTBASE is only important, if I load and start the kernel directly, without
the initialization from U-Boot. Am I right?

For information I attach the log I read out of memory at __log_buf
location... although I already posted that on the linuxppc-dev list...

Do you think, that there's maybe a hardware issue because of the timing
errors in the call trace?

Is this the reason for the strange behaviour of the gdb when trying to step
thru the code?

I mean - assuming that the hardware is correct - I should be able to do
"state-of-the-art" code stepping even at early stage like in
early_init_devtree, right?

Thanks!
Matthias
