[Buildroot] Login on a ttyS fails

[Stéphane Mancini]

Well, I've tried to launch ash after the boot instead of init.
I get a kernel panic :

init has generated signal 4 but has no handler for it

Kernel panic - not syncing: Attempted to kill init!

Rebooting in 180 seconds..


It seems that there is an "illegal instruction".

Is there a way to get the program counter and instruction code that
caused this signal ?
By the way, why the message states that "init" generates the signal
while I launched ash ?

Maybe there are troubles with my processor or the memory is getting
corrupted after I download the kernel....
