On a dual AthlonMP system running RELENG_6 from just a few hours ago (after the nswbuf fix, but before portsnap) I just got the panic at the end of this message while copying files over NFS when the server was busy with other things (both disk and network I/O). I don't have a crashdump unfortunately. Kernel options: SCHED_4BSD, PREEMPTION, ADAPTIVE_GIANT, ZERO_COPY_SOCKETS, SMP /Daniel Eriksson panic: lockmgr: locking against myself cpuid =3D 1 KDB: enter: panic [thread pid 41315 tid 100158 ] Stopped at kdb_enter+0x30: leave =20 db> tr Tracing pid 41315 tid 100158 td 0xc3e42480 kdb_enter(3228791923,1,3228786666,3833665712,17) at kdb_enter+48 panic(3228786666,3833665724,3833665812,3228466723,65) at panic+317 lockmgr(3269149032,8194,3269149068,3286508672,3833665796) at lockmgr+1021 vop_stdlock(3833665844,32,8194,3269148944,3833665872) at vop_stdlock+47 VOP_LOCK_APV(3229049824,3833665844,3833665852,3228161749,3238314952) at VOP_LOCK_APV+72 vn_lock(3269148944,8194,3286508672,72,3833666588) at vn_lock+314 vrele(3269148944,3833666000,3833666008,3833666012,3833666012) at vrele+252 nfs_lookup(3833666288,3833666204,3267556144,0,3833666316) at nfs_lookup+2274 VOP_LOOKUP_APV(3229049824,3833666288,3833666268,3286508672,3266082944) at VOP_LOOKUP_APV+72 lookup(3833666548,3286508672,0,0,0) at lookup+1134 namei(3833666548,3833666452,96,0,3286508672) at namei+1080 kern_stat(3286508672,3217022320,0,3833666664,100728578) at kern_stat+61 stat(3286508672,3833666820,8,3286505520,3252880840) at stat+47 syscall(59,59,59,134547418,134547405) at syscall+803 Xint0x80_syscall() at Xint0x80_syscall+31 --- syscall (188, FreeBSD ELF32, stat), eip =3D 671868991, esp =3D 3217022284, ebp =3D 3217023464 ---
