A newer source boots fine.
The only problem is that with the debugging options the system is
unbeleavable slow.
As an example the clock swi takes about 20% CPU...

I added the following:
options         KTR
options         KTR_EXTEND
options         KTR_ENTRIES=1024
options         KTR_COMPILE=0x3fffff
options         KTR_MASK=0x201208
options         KTR_CPUMASK=0x3
#options        KTR_VERBOSE

options         MUTEX_DEBUG
options         WITNESS
#options        WITNESS_DDB
options         WITNESS_SKIPSPIN

options         DIAGNOSTIC
options         INVARIANTS
options         INVARIANT_SUPPORT

What are the current recomended options?
Hopefully I can remove some of them without loosing too much information
for the failure case.
