If it's possible for you please turn on INVARIANTS in your kernel, I've
spread lots of KASSERTs around the code.

It would be also helpful if you could send me the on-disk config in
private mail. Use something like:
dd if=/dev/da1s1h skip=8 count=6 | tr -d '\000-\011\200-\377'
to get it.

Hm, I haven't seen this one before. It would be most helpful if you could
get a crashdump and a backtrace from gdb -k to debug this.
