Hi, At line 1156 of kernel/sched.c a function is called which only seems to exist on ia32 (show_trace). I guess this should be : #if __i386__ show_trace(p->thread.esp): #endif Cheers, Peter. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
