Hello, Can someone plese help me understand what is the problem? After fresh disk installation of freeBSD9.0 AMD64 from disk, I copied /usr/src/sys/am64/conf/GENERIC to KGDBKERNEL and added following lines to the file options GDB options DDB options KDB_UNATTENDED options BREAK_TO_DEBUGGER options ALT_BREAK_TO_DEBUGGER After this I rebuilt the Kernel and installed as below. make buildworld make buildkernel kernconf=KGDBKERNEL make installkernel kernconf=KGDBKERNEL Reboot into single user mode. mergemaster -p make installworld mergemaster Reboot. After this to setup KGDB I am using following document as my reference. http://chetanbl.blogspot.com/ To break into ddb I am trying issue sysctl debug.kdb.enter=1. Then the system becomes unresponsive. Also, I tried to enter ddb at booting stage by issuing boot -d command. Even then system becomes unresponsive. I need to solve this problem ASAP. Can someone helpme? Thanks, Nag
