--HlL+5n6rz5pIUxbD Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I get the following reproducible panic when booting a kernel with 'options NETGRAPH_BLUETOOTH_UBT' compiled in. The panic does not occur when loading the ng_ubt module from the loader. The kernel config is available at: http://people.freebsd.org/~brueffer/FANGORN panic: mtx_lock() of spin mutex (null) @ /usr/src/sys/netgraph/ng_base.c:11= 89 KDB: enter: panic Stopped at kdb_enter+0x32: leal 0(%esi),%esi db> tr Tracing pid 0 tid 0 td 0xc0809980 kdb_enter(c07a3b3d,c080bc80,c07a3012,c0c20cb0,c0809980) at kdb_enter+0x32 panic(c07a3012,0,c07b1161,4a5,cb) at panic+0x14d _mtx_lock_flags(c0836280,0,c07b1161,4a5,1000a) at _mtx_lock_flags+0x114 ng_findtype(c07b003f,101,c1046a00,0,0) at ng_findtype+0x2f ng_newtype(c07e8600,c079778f,101,0,c19d9a00) at ng_newtype+0x60 ubt_modevent(c196d500,0,0,c196d500,c1945630) at ubt_modevent+0x3f driver_module_handler(c196d500,0,c07e856c,c0c20d78,c050913f) at driver_modu= le_handler+0xa5 module_register_init(c07e8560,0,c1945a54,c1ec00,c1e000) at module_register_= init+0x75 mi_startup() at mi_startup+0xd6 begin() at begin+0x2c db> - Christian --=20 Christian Brueffer chris@unixpages.org brueffer@FreeBSD.org GPG Key: http://people.freebsd.org/~brueffer/brueffer.key.asc GPG Fingerprint: A5C8 2099 19FF AACA F41B B29B 6C76 178C A0ED 982D --HlL+5n6rz5pIUxbD Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQFB0C9WbHYXjKDtmC0RAkE4AKCt+HYiZJtCPiNhicDI/Kb6FCsDIwCcCZrP nVGqR1wB/btOJAtyjTCXmnA= =RFD2 -----END PGP SIGNATURE----- --HlL+5n6rz5pIUxbD--
