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

See the message "Boot device: /iommu/sbus/string/string/sd@3,0" for a solution.
