The boot drives are plugged directly into the Motherboard's SATA ports, which I believe is powered by a ULi M1689 chipset. I also have a Supermicro AOC-SAT2-MV8 PCI-X HBA card (http://www.supermicro.com/products/accessories/addon/AOC-SAT2-MV8.cfm) which has a Hercules-2 Rev. C0 SATA host controller built in. I've added ahci_load="YES" in my /boot/loader.conf and I can see that ahci.ko was loaded using klstat, but I do not see any drives appearing that use the ahci module. All drives are labeled /dev/ad* instead of /dev/ada* and hotswap doesn't work properly. Running dmesg |grep -i ahci comes back empty. >How-To-Repeat: 1. Boot computer 2. Run dmesg |grep -i ahci 3. Unplug drive, watch PC kernel panic >Fix: >Release-Note: >Audit-Trail: >Unformatted:
