Its true that I don't have any serial port, but even with this function
it doesn't boot any further.

I now tried to debug more of my problem with puts.
Unfortunately I didn't have much results.
I definitely now can say that I reach the last line of
void Timer::init() in ia32/timer-rtc.c.
(If I don't have sideeffects of puts and it is not buffered)

What is initialized next I can only guess.
It seems to be some kind of linker magic with the minilib/construction.c
which calls all the functions which are declared with

I have put a puts in uart_console_init() before the line 
with the if strstr -noserial. But this already doesn't seem to 
be called. Or it is just not compiled in?

I have also a puts in kdb.cpp in the void kdb::init() function.
But it is never reached.

Here I have some problems, why is the macro called with
but only a kdb::init exists.

And in uart_console.cpp it is
and a function uartconsole_init() exists.

Hmm I am little bit confused now and would appreciate some advice 
for debbuging.

Thanks a lot, Fabian
