I installed the rpm, rebooted, and at the grub prompt added numa=off, exact same symptoms. I also tried vga=0 to see if I can see more, and again no difference. After the ACPI messages,
ACPI: Power Button (FF) [PWRF] ACPI: Sleep Button (FF) [SLPF] ACPI: Processor [CPU0] (supports C1) ACPI: Processor [CPU1] (supports C1)
it stops. With vga=778, it prints also that it is switching to colour frame buffer device befor stopping. I can send you the boot.msg log from a successful boot of the -191 kernel, if you are interested.
I have an HDAMB running here and it works fine. It needed numa=off iommu=memaper=1 on older kernels. Also an BIOS upgrade is an good idea, the first BIOS I got was quite buggy and had several problems. For the ACPI issues you can try acpi=off (don't use the failsafe option, only acpi=off) -Andi
