Greetings, a fresh install off the 2014-10-26 bootonly iso, generates the following LOR: lock order reversal: 1st 0xfffffe00f7626b48 bufwait (bufwait) @ /usr/src/sys/kern/vfs_bio.c:3093 2nd 0xfffff8000404aa00 dirhash (dirhash) @ /usr/src/sys/ufs/ufs/ufs_dirhash.c:2 84 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe0120cd9650 kdb_backtrace() at kdb_backtrace+0x39/frame 0xfffffe0120cd9700 witness_checkorder() at witness_checkorder+0xdad/frame 0xfffffe0120cd9790 _sx_xlock() at _sx_xlock+0x75/frame 0xfffffe0120cd97d0 ufsdirhash_remove() at ufsdirhash_remove+0x37/frame 0xfffffe0120cd9800 ufs_dirremove() at ufs_dirremove+0x11b/frame 0xfffffe0120cd9860 ufs_remove() at ufs_remove+0x75/frame 0xfffffe0120cd98c0 VOP_REMOVE_APV() at VOP_REMOVE_APV+0xf7/frame 0xfffffe0120cd98f0 kern_unlinkat() at kern_unlinkat+0x209/frame 0xfffffe0120cd9ae0 amd64_syscall() at amd64_syscall+0x25a/frame 0xfffffe0120cd9bf0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xfffffe0120cd9bf0 --- syscall (10, FreeBSD ELF64, sys_unlink), rip = 0x800b5208a, rsp = 0x7fffffff eb58, rbp = 0x7fffffffeb70 --- it's not FATAL, but thought it worth mentioning. I haven't built, or installed world|kernel (yet). I also have dmesg(8) from that session, out of var/run/dmesg.boot, and would be happy to provide it, on request. Thank you for all your time, and consideration. --Chris
