Unfortunately this is the third time I report this. This panic occurs every 2 to 6 days. So far I've never managed to go over a week's uptime. Between crashes I've periodically updated to the latest RELENG_6. Here's the full backtrace: -- cut here -- (kgdb) bt fu #0 doadump () at pcpu.h:165 No locals. #1 0xc0582b84 in boot (howto=260) at ../../../kern/kern_shutdown.c:409 first_buf_printf = 1 #2 0xc0583117 in panic ( fmt=0xc0751ab1 "vm_page_unwire: invalid wire count: %d") at ../../../kern/kern_shutdown.c:565 bootopt = 260 newpanic = 0 buf = "vm_page_unwire: invalid wire count: 0", '\0' <repeats 218 times> #3 0xc06c4c00 in vm_page_unwire (m=0xc2669220, activate=0) at ../../../vm/vm_page.c:1197 No locals. #4 0xc05d4d75 in vfs_vmio_release (bp=0xda610da8) at ../../../kern/vfs_bio.c:1470 i = 3 m = 0xc2669220 #5 0xc05d8509 in getnewbuf (slpflag=0, slptimeo=0, size=16384, maxsize=16384) at ../../../kern/vfs_bio.c:1779 addr = 3663760120 bp = (struct buf *) 0xda610da8 nbp = (struct buf *) 0xda497348 defrag = 0 nqindex = 1 flushingbufs = 0 #6 0xc05d890e in getblk (vp=0xca945220, blkno=9273, size=16384, slpflag=0, slptimeo=0, flags=0) at ../../../kern/vfs_bio.c:2486 bsize = 16384 maxsize = 0 vmio = 1 offset = 151928832 bp = (struct buf *) 0x4000 bo = (struct bufobj *) 0xca9452e0 #7 0xc067faf6 in ffs_balloc_ufs2 (vp=0xca945220, startoffset=Unhandled dwarf expression opcode 0x93 ) at ../../../ufs/ffs/ffs_balloc.c:817 ip = (struct inode *) 0xca8eb8c4 dp = (struct ufs2_dinode *) 0xca21fd00 lbn = 9273 lastlbn = 11187 fs = (struct fs *) 0xc8622000 bp = (struct buf *) 0xda608af8 nbp = (struct buf *) 0xc05dea5f ump = (struct ufsmount *) 0xc8396a00 indirs = {{in_lbn = -2061, in_off = 1, in_exists = 0}, { in_lbn = -2061, in_off = 3, in_exists = 0}, {in_lbn = -8204, in_off = 1069, in_exists = 0}, {in_lbn = 8589934591, in_off = 0, in_exists = 0}, {in_lbn = -1828101238395240448, in_off = -1067988038, in_exists = -969433728}} nb = Unhandled dwarf expression opcode 0x93 (kgdb) -- and here -- My kernel looks like this: -- cut here -- machine i386 cpu I686_CPU ident ANONYMOUS maxusers 0 options HZ=100 options INCLUDE_CONFIG_FILE makeoptions DEBUG=-g options SCHED_4BSD options COMPAT_FREEBSD5 options KTRACE options _KPOSIX_PRIORITY_SCHEDULING options PREEMPTION options ADAPTIVE_GIANT options DDB options KDB options KDB_UNATTENDED options BLKDEV_IOSIZE=8192 options DFLDSIZ="(128UL*1024*1024)" options MAXDSIZ="(1024UL*1024*1024)" options MAXSSIZ="(384UL*1024*1024)" options SYSVSHM options SHMMAXPGS=4096 options SHMMAX="(SHMMAXPGS*PAGE_SIZE)+1" options SHMALL="(SHMMAXPGS*PAGE_SIZE)+1" options SYSVMSG options SYSVSEM options HWPMC_HOOKS options INET options INET6 options IPSTEALTH options TCP_DROP_SYNFIN options ZERO_COPY_SOCKETS options ACCEPT_FILTER_DATA options ACCEPT_FILTER_HTTP options FFS options SOFTUPDATES options UFS_DIRHASH options CD9660 options PSEUDOFS options PROCFS options FDESCFS options NULLFS options MD_ROOT options MAC options MAC_PARTITION options MAC_SEEOTHERUIDS device npx device apic device acpi device pmtimer device atkbdc device atkbd device psm device vga device sc device sio device speaker device fdc device hwpmc device isa device pci device ata device atadisk device atapicd options ATA_STATIC_ID device scbus device da device pass device atapicam device cd device miibus device fxp device em device usb device uhci device ohci device ehci device uhid device ukbd device ums device umass device ulpt device ucom device uplcom device md device loop device mem device io device random device ether device vlan device gif device gre device tun device tap device disc device bpf device pf device pflog device pty device snp -- and here -- VFS is tuned to vfs.read_max=16 vfs.ufs.dirhash_mem=1048576 vfs.ufs.dirhash_maxmem=67108864 What else can I do to help narrow down the origin of these crashes ? -- If it's there, and you can see it, it's real.
