Yes it is repeatable. Happens every reboot or shutdown. Controller works ok
all other time. (I have my homedir mounted to the raidarray.)

The source was synced and then I did a normal:
make buildworld
make buildkernel
make installkernel
reboot to singel user mode and mergemaster -p + make installworld +
mergemaster then reboot.

I will try to compile it again...
