You will need to compile DDB into the kernel, obtain DDB prompt after the panic and issue "bt" command. --MEatx1zidE5asLAI Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGjmL2C3+MBN1Mb4gRAk2BAJwN8S4SMw5MWkkai3Uow2AC9qo17QCgoEUI Y3VVDfnqJRVc8c3Yy/O6JHc= =C44m -----END PGP SIGNATURE----- --MEatx1zidE5asLAI--
