Kernel config file
Attached kernel config. My kernel is close to generic, extras are:
> options IPFIREWALL
> options IPDIVERT
> options DUMMYNET
then added these for debug, but the problem occurred without them:
> options KDB_UNATTENDED
> options DDB # Support DDB.
> options GDB # Support remote GDB.
> options INVARIANTS # Enable calls of extra sanity checking
> options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS
> options WITNESS # Enable checks to detect deadlocks and cycles
> options WITNESS_SKIPSPIN # Don't run witness on spinlocks for speed
You've probably got these from loader.conf, but I also have these:
