Gang, for a few weeks now I can't get a CURRENT system to boot. I am using the zfsloader and have root fs on ZFS. This has worked flawlessly for more than a year. The last message printed is "Mounting local file systems:" (from rc.d/mountcritlocal) and the system hangs until I push reset. Ctrl-C etc are ignored. However, CTRL-T says that mount is running in spa_namespace_lock, and the "r"untime increases at 1 second per second which looks like it is busy spinning on that lock. What can I do to diagnose and solve it? I do have a customized kernel config, which lookslike this. Anything wrong with it? # grep '^[^#]' sys/amd64/conf/HAL9000 cpu HAMMER ident HAL9000 makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols makeoptions WITH_CTF=1 # Run ctfconvert(1) for DTrace support options SCHED_ULE # ULE scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options INET6 # IPv6 communications protocols options IPSEC # IP (v4/v6) security options TCP_OFFLOAD # TCP offload options SCTP # Stream Control Transmission Protocol options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories options UFS_GJOURNAL # Enable gjournal-based UFS journaling options QUOTA # Enable disk quotas for UFS options MD_ROOT # MD is a potential root device options NFSCL # Network Filesystem Client options NFSD # Network Filesystem Server options NFSLOCKD # Network Lock Manager options NFS_ROOT # NFS usable as /, requires NFSCL options MSDOSFS # MSDOS Filesystem options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_PART_GPT # GUID Partition Tables. options GEOM_RAID # Soft RAID functionality. options GEOM_LABEL # Provides labelization options COMPAT_FREEBSD32 # Compatible with i386 binaries options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI options KTRACE # ktrace(1) support options STACK # stack(9) support options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options PRINTF_BUFR_SIZE=128 # Prevent printf output being interspersed. options KBD_INSTALL_CDEV # install a CDEV entry in /dev options HWPMC_HOOKS # Necessary kernel hooks for hwpmc(4) options MAC # TrustedBSD MAC Framework options KDTRACE_FRAME # Ensure frames are compiled in options KDTRACE_HOOKS # Kernel DTrace hooks options DDB_CTF # Kernel ELF linker loads CTF data options INCLUDE_CONFIG_FILE # Include this file in kernel options RACCT # Resource accounting framework options RACCT_DEFAULT_TO_DISABLED # Set kern.racct.enable=0 by default options RCTL # Resource limits options KDB # Enable kernel debugger support. options KDB_TRACE # Print a stack trace for a panic. options DDB # Support DDB. options MALLOC_DEBUG_MAXZONES=8 # Separate malloc(9) zones options SMP # Symmetric MultiProcessor Kernel device cpufreq device acpi options ACPI_DMAR device pci options PCI_IOV # PCI SR-IOV support device ahci # AHCI-compatible SATA controllers device ata # Legacy ATA/SATA controllers options ATA_STATIC_ID # Static device numbering device scbus # SCSI bus (required for ATA/SCSI) device ch # SCSI media changers device da # Direct Access (disks) device sa # Sequential Access (tape etc) device cd # CD device pass # Passthrough device (direct ATA/SCSI access) device ses # Enclosure Services (SES and SAF-TE) device atkbdc # AT keyboard controller device atkbd # AT keyboard device psm # PS/2 mouse device kbdmux # keyboard multiplexer device vga # VGA video card driver options VESA # Add support for VESA BIOS Extensions (VBE) device splash # Splash screen and screen saver support device sc device vt device vt_vga device vt_efifb device agp # support several AGP chipsets device ppbus # Parallel port bus (required) device miibus # MII bus support device loop # Network loopback device random # Entropy device device padlock_rng # VIA Padlock RNG device rdrand_rng # Intel Bull Mountain RNG device ether # Ethernet support device vlan # 802.1Q VLAN support device tun # Packet tunnel. device md # Memory "disks" device firmware # firmware assist module device bpf # Berkeley packet filter options USB_DEBUG # enable debug msgs device uhci # UHCI PCI->USB interface device ohci # OHCI PCI->USB interface device ehci # EHCI PCI->USB interface (USB 2.0) device xhci # XHCI PCI->USB interface (USB 3.0) device usb # USB Bus (required) device ukbd # Keyboard device umass # Disks/Mass storage - Requires scbus and da device sound # Generic sound driver (required) device virtio # Generic VirtIO bus (required) device virtio_pci # VirtIO PCI device device vtnet # VirtIO Ethernet device device virtio_blk # VirtIO Block device device virtio_scsi # VirtIO SCSI device device virtio_balloon # VirtIO Memory Balloon device options HYPERV # Hyper-V kernel infrastructure device hyperv # HyperV drivers options XENHVM # Xen HVM kernel infrastructure device xenpci # Xen HVM Hypervisor services driver device netmap # netmap(4) support device crypto # Required by IPSEC options EXT2FS options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=100 options IPDIVERT Regards, Jens -- Jens Schweikhardt http://www.schweikhardt.net/ SIGSIG -- signature too long (core dumped)
