I am getting oopses on shutdown, 'cause this bug is popping: static void apm_power_off(void) { unsigned char po_bios_call[] = { 0xb8, 0x00, 0x10, /* movw $0x1000,ax */ 0x8e, 0xd0, /* movw ax,ss */ 0xbc, 0x00, 0xf0, /* movw $0xf000,sp */ 0xb8, 0x07, 0x53, /* movw $0x5307,ax */ 0xbb, 0x01, 0x00, /* movw $0x0001,bx */ 0xb9, 0x03, 0x00, /* movw $0x0003,cx */ 0xcd, 0x15 /* int $0x15 */ }; /* * This may be called on an SMP machine. */ #ifdef CONFIG_SMP /* Some bioses don't like being called from CPU != 0 */ if (cpu_number_map(smp_processor_id()) != 0) { current->cpus_allowed = 1; schedule(); if (unlikely(cpu_number_map(smp_processor_id()) != 0)) BUG(); } #endif if (apm_info.realmode_power_off) machine_real_restart(po_bios_call, sizeof(po_bios_call)); else (void) set_system_power_state(APM_STATE_OFF); } Does this mean that after the schedule() kernel is still in CPU1 ??? Will add a couple ptintks.... This is 2.4.19-pre7+aa patches. TIA -- J.A.
