Elsukov <ae@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ae@FreeBSD.org --- Comment #12 from Andrey V. Elsukov <ae@FreeBSD.org> --- (In reply to Mark Johnston from comment #6) I saw similar panic and it was related with ifconfig destroy+create for interface reconfiguration. But last time when it was happened, panic has be= en occurred after ~15 minutes after reconfiguration was done. It is 13.0: Fatal trap 12: page fault while in kernel mode cpuid =3D 2; apic id =3D 04 fault virtual address =3D 0x100000390 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80cd32cb stack pointer =3D 0x28:0xfffffe00df5d79e0 frame pointer =3D 0x28:0xfffffe00df5d7a50 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 (swi4: clock (0)) trap number =3D 12 panic: page fault cpuid =3D 2 time =3D 1743588228 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00df5d7= 6a0 vpanic() at vpanic+0x182/frame 0xfffffe00df5d76f0 panic() at panic+0x43/frame 0xfffffe00df5d7750 trap_fatal() at trap_fatal+0x387/frame 0xfffffe00df5d77b0 trap_pfault() at trap_pfault+0x4f/frame 0xfffffe00df5d7800 trap() at trap+0x271/frame 0xfffffe00df5d7910 calltrap() at calltrap+0x8/frame 0xfffffe00df5d7910 --- trap 0xc, rip =3D 0xffffffff80cd32cb, rsp =3D 0xfffffe00df5d79e0, rbp = =3D 0xfffffe00df5d7a50 --- arptimer() at arptimer+0x6b/frame 0xfffffe00df5d7a50 softclock_call_cc() at softclock_call_cc+0x139/frame 0xfffffe00df5d7b00 softclock() at softclock+0x79/frame 0xfffffe00df5d7b20 ithread_loop() at ithread_loop+0x24d/frame 0xfffffe00df5d7bb0 fork_exit() at fork_exit+0x7e/frame 0xfffffe00df5d7bf0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe00df5d7bf0 --- trap 0, rip =3D 0, rsp =3D 0, rbp =3D 0 --- Uptime: 15d14h40m59s --=20 You are receiving this mail because: You are the assignee for the bug.=
