--- Comment #14 from Mark Johnston <ma...@freebsd.org> --- (In reply to Gregory Neil Shapiro from comment #10) So, if you're building a kernel from releng/14.0, GENERIC doesn't have debugging options enabled. DEBUG+=-g merely instructs the compiler to include debug symbols in the output, which helps debuggers but doesn't enable assertions, invariants checking, etc.. We don't include a debug kernel config on releng branches (this is a problem to be fixed). You can add the following lines (taken from GENERIC on main) to enable more checking which will hopefully catch a problem before the double fault occurs: # For full debugger support use (turn off in stable branch): options BUF_TRACKING # Track buffer history options DDB # Support DDB. options FULL_BUF_TRACKING # Track more buffer history options GDB # Support remote GDB. options DEADLKRES # Enable the deadlock resolver options INVARIANTS # Enable calls of extra sanity checking options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS options QUEUE_MACRO_DEBUG_TRASH # Trash queue(2) internal pointers on invalidation 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 options VERBOSE_SYSINIT=0 # Support debug.verbose_sysinit, off by default -- You are receiving this mail because: You are on the CC list for the bug.
