I have been trying to install 11.2 on my Supermicro AMD Athlon MP 2400+ dual cpu machine. This machine has been running FreeBSD 4.x for quite a long time but refuses to properly boot the 11.2 install media. It will get to the point of changing the video screen to show the kernel boot and it hangs having shown only a few lines. I've let it sit for a couple days wondering if it was doing something but nothing moved. So I suspect it's something in the kernel but have no way of seeing any error messages. The Athlon MP CPUs are 32-bit cpus but 686-class. I have not yet got to the point of building a custom kernel for this as my time is limited. This machine has a 3-ware hardware raid card in it
