Yesterday evening and today evening my system hangs with a page fault. I'm on CPU#1, I need to be on CPU#0, sleeping timeout waiting for CPU#0! syncing disks... Fatal trap 12: page fault while in kernel mode cpuid=1 lapic.id=0 fault virtual address = 0x10 fault code = supervisor-read, page not present instruction pointer = 0x8: 0xf0133110 stack pointer = 0x10:0xff803c5c frame pointer = 0x10:0xff803c70 code segment = base 0x0, limit 0xfffff, type=0x1b = DPL0, pres 1, def 32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = Idle mp_lock = 01000004 interrupt mask = tty <- SMP: XXX trap number = 12 panic: page fault cpuid 1 This was the output I noticed yestwerday evening. Today I cvsupped newly and build a new kernel. When the panic happened today at about 10pm, I compared the output with that above messages I wrote down, and everything is nearly the same, only the instruction stack and frame pointer were about off by one or two, because of the new kernel I think. What do you need to have more, so that you can figure out, what's going wrong ?
