Can't get as far as issuing a uname
>Description:
      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.


>How-To-Repeat:
      Just try installing any FreeBSD mentioned above on this kind of laptop. It hangs on kernel load.
>Fix:
      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.
