Kernel hangs in console_init()

[wei.li4 at elf.mcgill.ca]

Hi All,

I am working on linux 2.6.18-rc2 with my mpc875 demo board, I used 
Debugger LEDs to find that kernel stopped in:
	while (call < __con_initcall_end) {
		(*call)();
		call++;
        }
which is in console_init() of tty_io.c, what kind of problem could be?
What's the means of 'bctrl' instruction that I found in its assembler?

Thanks,
Wei
