At boot time it hit the vm page queue mutex/vnode interlock LOR, and it also hit a 'acquiring duplicate lock of same type: "vnode interlock"' when mounting the first nullfs instance, which may be related. panic: witness_destroy: lock (sleep mutex) vnode interlock is not initialized cpuid = 0 KDB: enter: panic [thread pid 148 tid 100132 ] Stopped at kdb_enter+0x30: leave db> wh Tracing pid 148 tid 100132 td 0xc572d180 kdb_enter(c0700f44,0,c07054af,f5774c38,c572d180) at kdb_enter+0x30 panic(c07054af,c06dff2c,c0716859,c070abdc,c7f66440) at panic+0x13e witness_destroy(c7f66440,c0700183,360,c0700545,c06df73d,c7f66440,c0716859,c070abdc,0,0) at witness_destroy+0x5a mtx_destroy(c7f66440,c7f663a8,8,c7f663a8,f5774cb8) at mtx_destroy+0xf2 vdestroy(c7f663a8,0,c070aaaf,271,0) at vdestroy+0x192 vnlru_free(c,0,c070aaaf,293,3e8) at vnlru_free+0x188 vnlru_proc(0,f5774d38,c06fe130,30c,c572d180) at vnlru_proc+0xb1 fork_exit(c058b9ee,0,f5774d38) at fork_exit+0x116 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xf5774d6c, ebp = 0 --- db> --zYM0uCDKw75PZbzx Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFCZsqrWry0BWjoQKURAmITAKCrHDoqe6ATJRL8K6STgsuGBdRyywCgyOaw PJJ1bL4RGXtc7RgCCe2DEPo= =DvXN -----END PGP SIGNATURE----- --zYM0uCDKw75PZbzx--
