Can't get as far as issuing a uname
      Attempting to install from CD amd64 FreeBSD 5.3, 5.4 RC4 or 6.0 on my Athlon 64 laptop causes the kernel to hang just after the loader prompt, irrespective of whether I disable ACPI, enable debug mode or any other option on the menu. Linux for amd64 works just fine. i386 FreeBSD works just fine, just not amd64 FreeBSD.

Spec is: Clevo D400J, Mobile Athlon 3400 with VIA K8M800 chipset and S3 Unichrome graphics. It has 1Gb of RAM and is pretty new - I bought it a few weeks ago. It's a pretty vanilla athlon64 laptop. It does NOT have a floppy drive.

      Just try installing any FreeBSD mentioned above on this kind of laptop. It hangs on kernel load.
      Is it possible that Mobile Athlon 64's are not supported? It's definitely an Athlon NOT a Sempron as I have x64 Linux running on it too.
