Oops, I contacted other panic. I used same kernel only enabled
INVARIANTS, INVARIANT_SUPPORT, WITNESS and WITNESS_SKIPSPIN.
debug.mpsafenet=1
debug.mpsafevm=1
net.isr.enable=1
no PREEMPTION
SCHED_ULE
INVARIANTS
INVARIANT_SUPPORT
WITNESS
WITNESS_SKIPSPIN
I'll try to disable INVARIANTS and INVARIANT_SUPPORT.
