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 ?
