From: "Alexander N.

Apparently, null_inactive tries to vput NULL lowervp vnode, but how lowervp has managed to become NULL is not immediately clear for me :( I have crash dump available, if anyone is interested. #0 dumpsys () at ../../../kern/kern_shutdown.c:492 #1 0xc01f4ab8 in boot (howto=0x104) at ../../../kern/kern_shutdown.c:335 #2 0xc01f4f07 in panic (fmt=0xc032cbd9 "bremfree: bp %p not locked") at ../../../kern/kern_shutdown.c:634 #3 0xc0222c29 in bremfree (bp=0xc6df7cf0) at ../../../kern/vfs_bio.c:539 #4 0xc0224261 in vfs_bio_awrite (bp=0xc6df7cf0) at ../../../kern/vfs_bio.c:1528 #5 0xc01d5ff4 in spec_fsync (ap=0xd197c9c8) at ../../../fs/specfs/spec_vnops.c:404 #6 0xc01d5bad in spec_vnoperate (ap=0xd197c9c8) at ../../../fs/specfs/spec_vnops.c:119 #7 0xc02ae621 in ffs_sync (mp=0xc1c69600, waitfor=0x2, cred=0xc0e5ac00, td=0xc03dc164) at vnode_if.h:441 #8 0xc022f4ea in sync (td=0xc03dc164, uap=0x0) at ../../../kern/vfs_syscalls.c:657 #9 0xc01f478d in boot (howto=0x100) at ../../../kern/kern_shutdown.c:244 #10 0xc01f4f07 in panic (fmt=0xc032e6da "vput: null vp") at ../../../kern/kern_shutdown.c:634 #11 0xc022cdbd in vput (vp=0x0) at ../../../kern/vfs_subr.c:1665 #12 0xc1cba606 in null_inactive (ap=0xd197caa8) at /usr/src/sys/modules/nullfs/../../fs/nullfs/null_vnops.c:728 #13 0xc022ce86 in vput (vp=0xd1fc5840) at vnode_if.h:654 #14 0xc0492287 in nfs_lookup (ap=0xd197cbc4) at /usr/src/sys/modules/nfsclient/../../nfsclient/nfs_vnops.c:808 #15 0xc022a8f9 in lookup (ndp=0xd197cc44) at vnode_if.h:45 #16 0xc022a3e4 in namei (ndp=0xd197cc44) at ../../../kern/vfs_lookup.c:168 #17 0xc0231375 in stat (td=0xd1899704, uap=0xd197cd20) at ../../../kern/vfs_syscalls.c:1976 #18 0xc02ec147 in syscall (frame={tf_fs = 0x2f, tf_es = 0xbfbf002f, tf_ds = 0xbfbf002f, tf_edi = 0xbfbffe3a, tf_esi = 0xbfbff938, tf_ebp = 0xbfbff998, tf_isp = 0xd197cd74, tf_ebx = 0x810a720, tf_edx = 0x1, tf_ecx = 0x3, tf_eax = 0xbc, tf_trapno = 0x0, tf_err = 0x2, tf_eip = 0x2830b9e3, tf_cs = 0x1f, tf_eflags = 0x200287, tf_esp = 0xbfbff50c, tf_ss = 0x2f}) at ../../../i386/i386/trap.c:1140 #19 0xc02dfc1d in syscall_with_err_pushed () #20 0x8094e81 in ??
