mount(1) at boot hangs in spa_namespace_lock
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
