https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231468 Bug ID: 231468 Summary: [acpi] [panic] 12.0-ALPHA6 vtnet0 cant setup virtq-intr when boot with no acpi kernel Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: koh@ksoftirqd.net Good morning. My QEMU Guest VPS has booted the kernel which removed ACPI to reduce capaci= ty in QEMU guest environment because kernel size is big since FreeBSD 12.0. Then the kernel panics as shown below. The kernel build uses src.txz from 12.0-ALPHA6. hint.acpi.0.disabled =3D "1" is not used, and only the "device acpi" is rem= oved in kernel build. # /etc/make.conf CC=3D/usr/local/bin/clang-devel CXX=3D/usr/local/bin/clang++-devel CPP=3D/usr/local/bin/clang-cpp-devel MODULES_OVERRIDE=3D cc dummynet # clang-devel -v clang version 8.0.0 Target: x86_64-portbld-freebsd12.0 Thread model: posix InstalledDir: /usr/local/llvm-devel/bin # dmesg when no ACPI w/ clang-devel vgapci0: Boot video device virtio_pci0: <VirtIO PCI Network adapter> port 0xc060-0xc07f mem 0xfebd1000-0xfebd1fff irq 11 at device 3.0 on pci0 vtnet0: <VirtIO Networking Adapter> on virtio_pci0 vtnet0: Ethernet address: fa:16:3e:67:7b:47 virtio_pci0: exhausted all interrupt allocation attempts vtnet0: cannot setup virtqueue interrupts Fatal trap 12: page fault while in kernel mode fault virtual address =3D 0x0 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff8044e0af stack pointer =3D 0x28:0xffffffff80a423a0 frame pointer =3D 0x28:0xffffffff80a423e0 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 0 (swapper) trap number =3D 12 panic: page fault time =3D 1 Uptime: 1s Automatic reboot in 15 seconds - press a key on the console to abort # dmesg when ACPI w/ clang-devel ---<<BOOT>>--- Copyright (c) 1992-2018 The FreeBSD Project.
