https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231468 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 capacity 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 = "1" is not used, and only the "device acpi" is removed in kernel build. # /etc/make.conf CC=/usr/local/bin/clang-devel CXX=/usr/local/bin/clang++-devel CPP=/usr/local/bin/clang-cpp-devel MODULES_OVERRIDE= 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 = 0x0 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff8044e0af stack pointer = 0x28:0xffffffff80a423a0 frame pointer = 0x28:0xffffffff80a423e0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) trap number = 12 panic: page fault time = 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.
