Just a quick note for anyone else that might be trying out the patch...
and I've built the whole system on both nodes without WITNESS and other debug- ging functionalities: =============================================================================== Index: /usr/src/sys/amd64/conf/GENERIC =================================================================== --- /usr/src/sys/amd64/conf/GENERIC (revision 265307) +++ /usr/src/sys/amd64/conf/GENERIC (working copy) @@ -76,14 +76,14 @@ 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 # 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 -options MALLOC_DEBUG_MAXZONES=8 # Separate malloc(9) zones +#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 # 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 +#options MALLOC_DEBUG_MAXZONES=8 # Separate malloc(9) zones # Make an SMP-capable kernel by default options SMP # Symmetric MultiProcessor Kernel ===============================================================================
I'd recommend leaving debugging options on (at minimum INVARIANTS and INVARIANT_SUPPORT). This will slow network performance but will allow a number of assertions to run that can make it a little easier to debug some issues.
