This is 10days old kernel panic, the same type I report before, but now I use dont-sync-on-panic sysctl, so some stack trace finally available: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x24 fault code = supervisor read, page not present instruction pointer = 0x8:0xc017fdab stack pointer = 0x10:0xcd36bb04 frame pointer = 0x10:0xcd36bb18 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 = 3 (g_up) trap number = 12 panic: page fault #0 0xc018a4bb in doadump () #1 0xc018ab44 in boot () #2 0xc018aee8 in panic () #3 0xc02992dc in trap_fatal () #4 0xc0298983 in trap () #5 0xc02897d8 in calltrap () #6 0xc01801f9 in _mtx_lock_sleep () #7 0xc01d3fac in bufdone () #8 0xc01d7e78 in cluster_callback () #9 0xc01d3f11 in bufdone () #10 0xc01d3d8e in bufdonebio () #11 0xc01d3b5c in biodone () #12 0xc01520ba in g_dev_done () #13 0xc01d3b5c in biodone () #14 0xc0154d28 in g_io_schedule_up () #15 0xc0154f38 in g_up_procbody () #16 0xc0173b51 in fork_exit ()
