I manage a 4 cores SMP server using Tyan B2881G28U4H [1] on which there are AIC-7902 and AMD-81x1. A MaxTronic RAID enclosure is connected to AIC-7902 and FreeBSD 6.0-RC1 is booted off from it. By default, FreeBSD couldn't start. Dumping the ahd state when probing the da and simply stopped. So I set the SCSI BIOS to restrict the device speed upto 80MB/s and the problem went away. After that, the machine runs flawlessly for 8 months. [1] http://www.tyan.com/products/html/gx28b2881_spec.html -- UEMURA (fka. MAENAKA) Tetsuya <maenaka@pluto.dti.ne.jp>
