I mean, even if the video driver crashes, I still want to have the ability to reboot the right way, avoiding corrupted files and WIP lose. Another thing is a non-critical module that can crash, but because not used by all apps on the machine, letting them ones that can continue run. But I don't know what is the approach of FreeBSD and devs about that. -- Florent Peterschmitt | Please: florent@peterschmitt.fr | * Avoid HTML/RTF in E-mail +33 (0)6 64 33 97 92 | * PDF for documents http://florent.peterschmitt.fr | Thank you :) [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iQEcBAEBAgAGBQJRteV1AAoJEMtO2Sol0IImQQYH/28fL6lukjwAWrVd0TJjTcff fcPQF1bzyaGnpSl6IBIqyxRz41vqvA9jfSgn4FrOMW1QIF3V4YBxu2X1D0dkpKiU Euo3qQC6awLnJOmCuuJu8hUYOG1T/UbPZMMAioTZ3RntmbHORQUTUHP5mSuX9d1q nPQ2iiswTLBBagtgOMecbwC5PhOfz67ZtmL2b3LrMfYIuvoOZ/pVExzaYZxthJ1R ztkRR8p4WzYW9mPGjr0OvYQFmJfFa6XxjOaxcVv73gq1aBzAgwjHjkI0BzhplLsR s7jkqhTRjOB4JTCgCRenYlPhWNpvstyvOYZhs9TwGwmf/7d0aO/alIUPca8WZIs= =So8p -----END PGP SIGNATURE-----
