Developers expecting to perform active deugging should add ddb_enable=3DNO or change the script to not perform at textdump and reboot the machine. This is another step toward hopefully shipping 8.0 with DDB built in and generating useful crash dumps. The security implications of doing so need to be carefully considered and in particular the GENERIC kernel will probably want to be shipped with at least the options DDB_UNATTENDED and SC_DISABLE_KDBKEY. The fact that the watchdog driver changes it's behavior based on DDB_UNATTENDED is probably a bug that should be fixed. -- Brooks ----- Forwarded message from Brooks Davis ----- =46rom: Brooks Davis Date: Mon, 21 Apr 2008 18:18:00 +0000 (UTC) To: brooks@FreeBSD.ORG Subject: [src] cvs commit: src/etc/defaults rc.conf brooks 2008-04-21 18:17:48 UTC FreeBSD src repository Modified files: etc/defaults rc.conf=20 Log: Change the default of ddb_enable to YES so we default to generating textd= umps on panic.
