I made some more progress. After adding 3 lines for MMU support with the BDI
I can debug the startup up to kernel_start using BDI. 

Afterwards my console changes the baudrate for still unknown reasons.

Analysing the __log_buf I get the following output
(gdb) x/s &__log_buf
0xc01accfc <ratelimit_lock.9>:   "<4>Linux version 2.6.10

Any hint would be greatly appreciated.

Best regards
