I have H8QGi-F, 2x 6172, 8ea x 4GB memories and 2 disks at SATA port with Adaptec Embedded RAID1 enabled and it is locked up at Ubuntu 10.10, 11.04 and 11.10 installation.
Actually it wasn’t locked up, it was taking a long time for the next step on the installation, if you enable IOMMU from “North Bridge Configuration” then you don’t see the slow installation.
