Also Paul, Now that is working do me a favor and try to compile the userland and kernel with that bsd.mp acpi enable kernel. Also, try if possible to make transfer of huge files between two boxes well connected to try to at a minimum get close to 100Mb/sec of transfer, or more if you have Gb access. In my case, it will crash every time still. Then the compile is ok with bsd, but still crash with bsd.mp in some cases. I am curious to know if that specific to my hardware, or if others have the same problem. Thanks Daniel.
