I have a system running FreeBSD 8.0-RC1 that contains 3x Sil3124 PCI-E SATA controller cards. Each card has 3x Sil3726 Port Multipliers attached (5 slots per SATA PM). The problem is that the disks are often not all detected by FreeBSD, even though the controller Option ROMs list all of the installed physical disks. Which drive(s) are not detected seems to vary with each boot. All of the port multipliers are detected every boot, it's just the drives which aren't getting probed. I've tried the following patch, http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/129784 , which may have helped - it picks up 6-8 out of 9 disks, but obviously that's not ideal. The motherboard BIOS version is current, as is the firmware for the SATA controllers. Does anyone have any ideas or other patches that I may try? Thanks, Steve Polyack
