Possibly it could be this?
/* Task might have expired already, but not scheduled off yet */ if (p->array != rq->active) { set_tsk_need_resched(p); <-- [1] return; }
static inline void set_ti_thread_flag(struct thread_info *ti, int flag) { set_bit(flag,&ti->flags); <-- [2] }
static __inline__ void set_bit(int nr, volatile unsigned long * addr) { __asm__ __volatile__( LOCK_PREFIX "btsl %1,%0" :"=m" (ADDR) :"Ir" (nr)); }
Code; 00000000 Before first symbol 00000000 <_EIP>: Code; 00000000 Before first symbol 0: 0f ab 50 08 bts %edx,0x8(%eax) Code; 00000004 Before first symbol 4: 8d 65 f4 lea 0xfffffff4(%ebp),%esp
So addr was NULL it seems, perhaps we're not supposed to be in here in the first place ?
