In your kernel config, remove these lines if they exist:
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 can leave the "options {K,D,G}DB" lines, they incur virtually now
performance costs.
You would get more help (possibly) if you tried posting on current@
