In a module, "cli" should not be an illegal opcode, but in user-mode code it is. But, you should not be using 'cli' anywhere. Instead, you should use a spin-lock to protect a critical section. Check the coding in any network drivers to see how it is done. Cheers, Dick Johnson Penguin : Linux version 2.6.16.24 on an i686 machine (5592.72 BogoMips).
