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... /Magnus
