This is interesting because the 29160 is exactly the controller with
which I had all my problems, but I was running it with disks only.

I guess his MB is not an AM2 socket

Right, my system board is a Tyan Thunder i7520 (S5360) server board (with only one Xeon single core CPU). 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
