This is likely a NULL pointer dereference.
I was able to capture the whole error, there are 2 instruction pointers that I checked: FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfec08000 cpu1 (AP): apic id: 12, version: 0x00040011, at 0xfec08000 io0 (APIC): apic id: 13, version: 0x00170011, at 0xfec00000 Fatal trap 12: page fault while in kernel mode cpuid = 0; lapic.id = 00000000 fault virtual address = 0xcf8f9fec fault code = supervisor write, page not present instruction pointer = 0x8:0xc032188c stack pointer = 0x10:0xc04c7bbc frame pointer = 0x10:0xc04c7bbc code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) trap number = 12 panic: page fault cpuid = 0; lapic.id = 00000000 Uptime: 1s WARNING: Driver mistake: make_dev(geom.ctl) called before SI_SUB_DRIVERS (kgdb) l *0xc032188c 0xc032188c is in cpu_thread_setup (../../../i386/i386/vm_machdep.c:312). 307 { 308 309 td->td_pcb = 310 (struct pcb *)(td->td_kstack + KSTACK_PAGES * PAGE_SIZE) - 1; 311 td->td_frame = (struct trapframe *)((caddr_t)td->td_pcb - 16) - 1; 312 td->td_pcb->pcb_ext = NULL; 313 } 314 315 /* 316 * Initialize machine state (pcb and trap frame) for a new thread about to Fatal trap 12: page fault while in kernel mode cpuid = 0; lapic.id = 00000000 fault virtual address = 0x38 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01f813e stack pointer = 0x10:0xc04c776c frame pointer = 0x10:0xc04c776c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) trap number = 12 panic: page fault cpuid = 0; lapic.id = 00000000 Uptime: 1s (kgdb) l *0xc01f813e 0xc01f813e is in device_shutdown (../../../kern/subr_bus.c:1499). 1494 } 1495 1496 int 1497 device_shutdown(device_t dev) 1498 { 1499 if (dev->state < DS_ATTACHED) 1500 return (0); 1501 return (DEVICE_SHUTDOWN(dev)); 1502 } 1503 Manfred ================================== || [EMAIL PROTECTED] || || Ph.
