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 ?
