Two things to do for you: 1) Please check that the problem is still there with a more recent version of OS, by upgrading to the top of RELENG_6, because it can be that it's been already found and fixed. 2) If above isn't possible, or doesn't fix the problem, please get yourself familiar with the kernel debugging, and provide a useful stack trace that developers can use to try to diagnose the problem: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kernel= debug.html Cheers, --=20 Ruslan Ermilov ru@FreeBSD.org FreeBSD committer --liOOAslEiF7prFVr Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFFT0hXqRfpzJluFF4RAmO8AJ0cCSJ6go6FYmzXYV5+AdXghcUC9QCfdrjd UgDUYFc5DzfrOtdY06rj1wo= =ORgF -----END PGP SIGNATURE----- --liOOAslEiF7prFVr--
