Thank you, but "goto opps", not "goto oops" in patch. 
>Didn't you run the  modules_install after changed .config?
No, I'm don't run modules_install. I'm build all modules first and use it (if required) for all my kernel's... And I have one init script, where :
...
/sbin/modprobe vfat
...
I want test to load any modules. Why not ?
