One way only - serial console.

1.
Actualy i use old and stupid source code modifying.
i add 5-20 printk in the suspicious places and watch serial
console. This process is tiresome.

2.
Advanced is kgdb kernel pathes. http://kgdb.linsyssoft.com/
In theory kgdb allow debug Your kernel without source
modifiyng. kgdb developers will not race with current kernel,
so any must applay kgdb to current kernel by himself.
i wont do than and use 1st method.

Oft debuging does not got answer, what is broken.
