--YiEDa0DAkWCtVeE4 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I've been kicking around arla from CVS against a pretty recent -current. I can load nnpfs, start arlad, get and list tokens, but attempting to "ls /afs" results in a seemingly permanent hang after showing this: lock order reversal: 1st 0xc1c8dd64 user map (user map) @ /usr/current/src/sys/vm/vm_map.c:2208 2nd 0xc2088ce8 ufs (ufs) @ /usr/current/src/sys/vm/vm_object.c:1053 KDB: stack backtrace: db_trace_self_wrapper(c0b49785,c878ea98,c07d02ae,c0b4c052,c2088ce8,...) at db_trace_self_wrapper+0x26 kdb_backtrace(c0b4c052,c2088ce8,c0b4049d,c0b4049d,c0b6d558,...) at kdb_backtrace+0x29 witness_checkorder(c2088ce8,9,c0b6d558,41d,c0783fb4,...) at witness_checkorder+0x6de __lockmgr_args(c2088ce8,80400,c2088d04,0,0,...) at __lockmgr_args+0x777 ffs_lock(c878eba0,0,9f,80400,c2088c90,...) at ffs_lock+0x8a VOP_LOCK1_APV(c0c3e160,c878eba0,c0c56080,c2088c90,80400,...) at VOP_LOCK1_APV+0xa5 _vn_lock(c2088c90,80400,c0b6d558,41d,28725000,...) at _vn_lock+0x5e vm_object_sync(c2010174,0,0,2000,0,...) at vm_object_sync+0x186 vm_map_sync(c1c8dd20,28725000,28727000,0,0,...) at vm_map_sync+0x281 msync(c1ebc000,c878ecf8,c,c0b4ca63,c0c1aed8,...) at msync+0x6c syscall(c878ed38) at syscall+0x2a3 Xint0x80_syscall() at Xint0x80_syscall+0x20 --- syscall (65, FreeBSD ELF32, msync), eip =3D 0x2827007f, esp =3D 0x2857374c, ebp =3D 0x285737c8 --- I've gotten remote GDB set up and working at least with the kernel sources... I'm not sure if it'll let me step into nnpfs correctly or not. I'm rebuilding a kernel with options as described here: http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-deadloc= ks.html to see if I can glean any more info. Anyone (Robert maybe?) got any other tips for me? --=20 Alec Kloss alec@SetFilePointer.com IM: angryspamhater@yahoo.com PGP key at http://pgp.mit.edu:11371/pks/lookup?op=3Dget&search=3D0xA241980E "No Bunny!" -- Simon, from Frisky Dingo --YiEDa0DAkWCtVeE4 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFIj9Cx2s33paJBmA4RAiOzAJwJ2V9ASOINfOEMsr9Jwon84jT00QCcDvJp rFa68xMWxUt4ZCmjy02V194= =5GeD -----END PGP SIGNATURE----- --YiEDa0DAkWCtVeE4--
