If that is indeed the source of your change_bit function then there is a problem. However in my kernel tree there is a LOCK_PREFIX in the definition of the atomic version. I don't have your exact source tree handy, but on a local RHEL4 system, the LOCK_PREFIX is still there: static inline void change_bit(int nr, volatile unsigned long * addr) { __asm__ __volatile__( LOCK_PREFIX "btcl %1,%0" :"=m" (ADDR) :"Ir" (nr)); } - R. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
