ok, I'll need to study this. I've in the kernel: # Debugging support. Always need this: options KDB # Enable kernel debugger support. options KDB_TRACE # Print a stack trace for a panic. # For full debugger support use (turn off in stable branch): options DDB # Support DDB options GDB # Support remote GDB options DEADLKRES # Enable the deadlock resolver options INVARIANTS # Enable calls of extra sanity checking options INVARIANT_SUPPORT # required by INVARIANTS options WITNESS # Enable checks to detect deadlocks and cycles options WITNESS_SKIPSPIN # Don't run witness on spinlocks for speed options MALLOC_DEBUG_MAXZONES=8 # Separate malloc(9) zones so I'm missing DEBUG_LOCKS, DEBUG_VFS_LOCKS and DIAGNOSTIC from the handbook list. What about all debug options in GENERIC which are not mentioned in your link? Specifically, do I need to have DEADLKRES? I've never used trace. Also, I'm getting a panic, so cannot run ps, I think.
