The Adaptec SCSI is a PCI and the Areca RAID a PCIe controller. I guess some more facts are needed to track this down. Does it make troubles with more then one CPU core and also more then 3.5 GB RAM running on FreeBSD/amd64? If yes, then I'm not surprised that only a few people see this behavior. I think the following informations would be needed to narrow down the affected environment: - FreeBSD version 6.x, 7.x or 8-CURRENT and i368 or amd64 - make and model of system board - make and model of SCSI controller and which driver - on board SCSI controller or PCI / PCI-X / PCIe - device types connected to the SCSI, eg. disk, tape - number of cpu cores - amount of memory So for my system which works fine, this would be: - FreeBSD/amd64 6.3-RELEASE - Tyan Thunder i7520 (S5360) - Adaptec 29160 Ultra160 SCSI adapter (ahc) - PCI - tape drive (DLT-8000) - 1 cpu core - 4 GB RAM bye Fabian
