X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 07 Jun 2005 10:30:37 -0000 Hi, I want to produce a backtrace of a kernel panic ("lockmgr: locking against myself" while accessing a msdosfs, very easy to reproduce for me: let rythmbox rescan the music collection (automatic operation at startup) which resides on a msdosfs). Unfortunately kgdb produces a lot of unresolved symbols since I load msdosfs as a module. The straigt forward way of debugging this is to build msdosfs into the kernel (or to use firewire when I'm back at my place), but I like to know if there's another way too (loading the modules into kgdb).
