https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235856 --- Comment #7 from Alex Dupre <ale@FreeBSD.org> --- I'm not 100% sure, but it looks like it didn't happen recently, so it might= be fixed. The last reboot of that machine was caused by this: nvme1: Missing interrupt nvme0: Missing interrupt ena0: Keep alive watchdog timeout. ena0: Trigger reset is on ena0: device is going DOWN nvme1: cpl does not map to outstanding cmd cdw0:00000000 sqhd:000a sqid:0001 cid:000b p:0 sc:00 sct:0 m:0 dnr:0 nvme1: Resetting controller due to a timeout. nvme1: resetting controller nvme1: temperature threshold not supported nvme1: aborting outstanding i/o nvme1: READ sqid:1 cid:11 nsid:1 lba:82665664 len:64 nvme1: ABORTED - BY REQUEST (00/07) sqid:1 cid:11 cdw0:0 nvme1: Missing interrupt ena0: ena0: device is going UP link is UP nvme1: Resetting controller due to a timeout. nvme1: resetting controller nvme1: temperature threshold not supported nvme1: aborting outstanding i/o nvme1: READ sqid:1 cid:11 nsid:1 lba:101778688 len:64 nvme1: ABORTED - BY REQUEST (00/07) sqid:1 cid:11 cdw0:0 nvme1: aborting outstanding i/o nvme1: READ sqid:1 cid:21 nsid:1 lba:93070656 len:64 nvme1: ABORTED - BY REQUEST (00/07) sqid:1 cid:21 cdw0:0 nvme1: aborting outstanding i/o nvme1: WRITE sqid:1 cid:4 nsid:1 lba:87852928 len:64 nvme1: ABORTED - BY REQUEST (00/07) sqid:1 cid:4 cdw0:0 Fatal trap 12: page fault while in kernel mode cpuid =3D 2; apic id =3D 02 fault virtual address =3D 0x18 fault code =3D supervisor write data, page not present instruction pointer =3D 0x20:0xffffffff80ae362e stack pointer =3D 0x28:0xfffffe00741bc1c0 frame pointer =3D 0x28:0xfffffe00741bc200 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 (irq258: nvme0) trap number =3D 12 panic: page fault cpuid =3D 2 time =3D 1563188396 KDB: stack backtrace: #0 0xffffffff80be7957 at kdb_backtrace+0x67 #1 0xffffffff80b9b543 at vpanic+0x1a3 #2 0xffffffff80b9b393 at panic+0x43 #3 0xffffffff81074bff at trap_fatal+0x35f #4 0xffffffff81074c59 at trap_pfault+0x49 #5 0xffffffff8107427e at trap+0x29e #6 0xffffffff8104f6f5 at calltrap+0x8 #7 0xffffffff807674f6 at nvme_qpair_complete_tracker+0x166 #8 0xffffffff807672b4 at nvme_qpair_process_completions+0x94 #9 0xffffffff80b5edf7 at ithread_loop+0x1a7 #10 0xffffffff80b5bf13 at fork_exit+0x83 #11 0xffffffff810506ee at fork_trampoline+0xe Uptime: 5d3h3m9s --=20 You are receiving this mail because: You are the assignee for the bug.=
