https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207432 Bug ID: 207432 Summary: panic: nvme_ctrlr_intx_handler Product: Base System Version: 10.3-BETA2 Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: wac@google.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org I've created a 10.3-BETA2 image for Google Compute Engine using swills' script and am getting a panic on boot when the VM is configured with Local SSD as NVMe (--local-ssd interface=3D"NVME"). This is a regression from 10.2-RELEASE which will boot successfully with an identical configuration. Fatal trap 12: page fault while in kernel mode cpuid =3D 0; apic id =3D 00 fault virtual address =3D 0x60 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80e16019 stack pointer =3D 0x28:0xfffffe01bfff59c0 frame pointer =3D 0x28:0xfffffe01bfff59e0 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 (irq11: virtio_pci0+) [ thread pid 12 tid 100039 ] Stopped at nvme_ctrlr_intx_handler+0x39: cmpq $0,0x60(%rdi) db> bt Tracing pid 12 tid 100039 td 0xfffff8000422e000 nvme_ctrlr_intx_handler() at nvme_ctrlr_intx_handler+0x39/frame 0xfffffe01bfff59e0 intr_event_execute_handlers() at intr_event_execute_handlers+0xab/frame 0xfffffe01bfff5a20 ithread_loop() at ithread_loop+0x96/frame 0xfffffe01bfff5a70 fork_exit() at fork_exit+0x9a/frame 0xfffffe01bfff5ab0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe01bfff5ab0 --- trap 0, rip =3D 0, rsp =3D 0, rbp =3D 0 --- Later with kgdb looks like ctrlr->ioq is null.
