svn r262799, witness disabled, explodes much later here, also system 
with iwn if it's related.

pid 911 was:
  65  911    1   0  52  0 14556   0 select   Ds    -  0:00.00 [dhclient]

no trace with symbols because kgdb doesn't like that clang creates.
Dwarf Error: wrong version in compilation unit header (is 4, should be 
2) [in module /boot/kernel/kernel.symbols]
