kernel memory mapping problem

Dear all,

I have a problem that :

the function is :

int func()
{
	unsigned char tmp[10];
	unsigned char * p;

	p = __pa(tmp);
	...
	pI2cRxBD -> bd_addr = p;
	...
	...
}
when run this module( lsmod mymodule.o ), kernel is always dead. Are there any errors of this function ?

Any help is appreciated!
