DEBUG+=3D-g merely instructs the compiler to in= clude 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 proble= m 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):=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 options BUF_TRACKING # Track buffer history=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20 options DDB # Support DDB.=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 options FULL_BUF_TRACKING # Track more buffer history=20=20= =20=20=20=20=20=20=20=20=20=20=20 options GDB # Support remote GDB.=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 options DEADLKRES # Enable the deadlock resolver=20= =20=20=20=20=20=20=20=20=20 options INVARIANTS # Enable calls of extra sanity chec= king=20 options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20 options QUEUE_MACRO_DEBUG_TRASH # Trash queue(2) internal pointers = on invalidation=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 options WITNESS # Enable checks to detect deadlocks= and cycles=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20 options WITNESS_SKIPSPIN # Don't run witness on spinlocks for speed=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20 options MALLOC_DEBUG_MAXZONES=3D8 # Separate malloc(9) zones=20=20= =20=20=20=20=20=20=20=20=20=20=20=20 options VERBOSE_SYSINIT=3D0 # Support debug.verbose_sysinit, = off by default --=20 You are receiving this mail because: You are on the CC list for the bug.
