It's rather unlikely that anyone will be able to help, unless you make your code
and configuration available.
Ok, Udo. I'd like to show small patches instead of showing my code but I
think it's operation is the same with my code and it reproduced the same
result.

The watchdog is enabled by enable_watchdog via fiasco_watchdog_enable()
in sys/kdebug.h. The kernel configuration file is attached. Is this
enough that someone helps me? :) Please, give me any advice.
