From a dump of a panic that occurred on 2015-09-30.=20 The events preceding this panic were memorable. The notebook had a wireless network connection and the wireless router was working, but the OS could not get Internet service.=20 I tried to reproduce the panic, it didn't occur until long after I pressed = the button in the Adobe dialogue.=20 The panic occurred after I did something to gain Internet connectivity. Probably a restart of the network software.=20 =E2=80=A6=20 <118>Sep 30 03:24:40 cces3-gjp4-pc-bsd-ergo-vista-621 wpa_supplicant[453]: ioctl[SIOCS80211, op=3D26, val=3D0, arg_len=3D0]: Operation not supported Fatal trap 12: page fault while in kernel mode cpuid =3D 1; apic id =3D 01 fault virtual address =3D 0x0 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80914f89 stack pointer =3D 0x28:0xfffffe00921afa20 frame pointer =3D 0x28:0xfffffe00921afb20 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 12 (irq257: wpi0) trap number =3D 12 panic: page fault cpuid =3D 1 KDB: stack backtrace: #0 0xffffffff80ac8d27 at kdb_backtrace+0x67 #1 0xffffffff80a85059 at vpanic+0x189 #2 0xffffffff80a84ec3 at panic+0x43 #3 0xffffffff80f055e5 at trap_fatal+0x355 #4 0xffffffff80f05926 at trap_pfault+0x326 #5 0xffffffff80f04f84 at trap+0x464 #6 0xffffffff80ee8b9a at calltrap+0x8 #7 0xffffffff80a4761a at intr_event_execute_handlers+0x1da #8 0xffffffff80a47a26 at ithread_loop+0xa6 #9 0xffffffff80a4472c at fork_exit+0x9c #10 0xffffffff80ee90ce at fork_trampoline+0xe Uptime: 11m8s =E2=80=A6 --=20 You are receiving this mail because: You are the assignee for the bug.=
