Further discovery shows the problem is in some SCSI driver code. I remember that someone had panic problem when installing the FreeBSD, but I am not sure it is related to this complicated SCSI issue. disklabel can label raw-raw disks if one SCSI controller installed, and there are one or two disks on the SCSI bus. (confirmed) Problems -- Installation problem with SCSI: If more then two disks on the SCSI bus, then installation can panic when probing the SCSI host adapters (I am using NCR) if there are bad labeling or unlabeled disk(s) on the SCSI bus. However, if using multiple SCSI controllers (host adapters), and put only two or less disk on each SCSI controller, then the installation will work. The problem after installation: If one SCSI controller and two SCSI disks are installed on system. No problem. If one or more SCSI controllers installed, but only two SCSI disks installed, no problem either. However, if more then two SCSI disks installed, regardless how many SCSI controller installed, the disklabel will not work properly in either panic or not recognizing the unlabeled disks and having the following errors, for sd0, sd1, ...
