The SCSI bus is hung. Perhaps an external device is turned off.

Cause

This message appears near the beginning of rebooting, immediately after a Boot device: ... message. Then, the system hangs. The problem is conflicting SCSI targets for a non-boot device. Having an external device turned off is unlikely to cause this problem.

Action

For a solution, refer to "Boot device: /iommu/sbus/directory/directory/sd@3,0".
