My big problem is that the system is not performing memory dumping and/or automatic reoboot, it just stays there. Here' console output: em0: watchdog timeout -- resetting kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode cpuid = 0; apic_id = 00 fault virtual address = 0x14 fault code = supervisor read, page not present intruction pointerr = 0x20:0xc056e2ce stack pointer = 0x28:0xe537fc08 frame pointer = 0x28:0xe537fc28 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 29 (em0 taskq) trap number = 12 panic: page fault cpuid = 0 It just stays there, unresponsive (no automatic reboot). Any ideas?
